Whether you are completing a job application, reviewing a contract, or marking an inspection sheet, knowing how to add clear symbols to a PDF can save time. Checkmarks, circles, and crosses are useful for forms, approval workflows, surveys, checklists, tax documents, and scanned files in many industries, including HR, legal, finance, and more.
This guide explains how to add a checkmark to a PDF, how to add a circle to a PDF, and how to add a cross to a PDF using pdfFiller. It also covers the difference between static marks and fillable fields, text-based tick symbols, mobile editing, scanned PDFs, and alternative tools.
Quick answer: How do you mark a PDF?
To add a mark to a PDF with pdfFiller:
- Open pdfFiller and sign in.
- Upload the PDF from your computer or import it from Google Drive or another supported cloud storage service.
- Open the document in editing mode.
- Select Check, Cross, or Circle from the toolbar.
- Click the desired location on the PDF page.
- Move or resize the mark as needed.
- Select Done.
- Save, download, print, email, or export the updated PDF.
The best method depends on the file. A fillable PDF may already contain interactive check boxes, while a static or scanned PDF usually requires you to manually add tick marks with a mark tool, text box, or annotation feature.
How to add a checkmark to a PDF with pdfFiller
Adding a checkmark can be as easy as a built-in function of a comprehensive PDF editing platform.
1. Upload the PDF file
Open pdfFiller in your browser and upload the document you want to edit. By clicking + Add new, you can select a file from your computer, drag and drop it into the upload area, or import it from a connected cloud storage account such as Google Drive.

The pdfFiller Add new menu shows options to upload a document from a device, Google Drive, Dropbox, OneDrive, Box, a URL, or email.
If the document is already stored in your pdfFiller account, open it from the dashboard. The PDF document will then appear in the editor.
2. Select the Check tool
With the document open in editing mode, select the Check or check mark icon from the toolbar.
The Check tool places a static, visible checkmark on the page. It is useful when you need to:
- Confirm a completed item
- Mark an existing box
- Indicate approval or selection
- Add a tick mark to a static PDF form
- Annotate a scanned PDF
A static check mark is not an interactive checkbox. It remains visible in the edited PDF, but another user cannot click it to change its state.
3. Place and resize the checkmark
Click where you want the checkmark symbol to appear. Zoom in when marking a small box or closely spaced form fields.

The selected Check tool in pdfFiller places a resizable checkmark on the document and opens controls for alignment, color, deletion, and additional settings.
Drag the mark to the desired location and resize it using the available handles. Keep the mark inside the intended field and avoid covering nearby text.
If you add several checkmarks, use approximately the same size and alignment throughout the document.
4. Save or download the updated PDF
When the placement looks correct, select Done. You can then save the file to your account, download it, print it, email it, or export it to supported cloud storage.

The orange Done button in pdfFiller completes the current editing session, with download, print, and additional document options displayed nearby.
Reopen the downloaded file before sharing it to confirm that the mark appears correctly.
Checkmark versus checkbox: Which should you use?
A checkmark and a checkbox serve different purposes.
A checkmark is a static annotation. Use it when you are filling out the document yourself and need to place a visible tick mark in an existing box or beside an option.
A checkbox field is interactive. It allows another person to click the box and switch it between checked and unchecked states.

Add Checkbox fields in pdfFiller to create fillable PDF forms that let recipients select one or more predefined options.
Use a checkbox field when:
- You are creating a PDF form
- Other people need to complete it
- The field should remain interactive
- The document will be reused
In pdfFiller, interactive check boxes can be added through the Create form or Add Fields area by selecting Checkbox from the form fields list.
Use the Check tool for a visible mark. Use fillable fields when recipients need to interact with the PDF form.
How to add a circle to a PDF
Upload the PDF to pdfFiller and open it in editing mode (Edit & fill). Select the Circle tool from the toolbar.
A circle is useful for:
- Highlighting a number
- Marking a survey answer
- Drawing attention to a contract clause
- Identifying an item that needs review
- Annotating scanned PDFs
- Providing visual feedback
Click and drag to draw the circle around the relevant content. Position it so the shape frames the information without covering the text.
Resize or move the circle when necessary. Review the full PDF page, select Done, and download or save the updated file.
How to add a cross to a PDF
Select the Cross or X mark tool in the editing toolbar.
A cross can indicate:
- A rejected option
- An incorrect field
- A “No” response
- An item that does not apply
- A section requiring correction
Click the intended location and place the cross inside the correct box or area. Precision is important on structured forms because a misplaced mark may change the meaning of the response.
Resize the cross so it remains consistent with the other marks in the document. Save the edited PDF and verify that the cross appears correctly in the downloaded file.
How to insert a checkmark symbol as text
A text-based checkmark is useful when the symbol must appear inside a sentence, text box, comment, or other free-text area.
Common Unicode checkmark symbols include:
- ✓
- ✔
- ☑
Add a text box
Select Text box or the Text tool, then click where the symbol should appear. Paste the preferred tick symbol into the text box and adjust its size and position.
This method provides more control over formatting than a fixed mark tool and can help the symbol match the surrounding text.
Use Character Map on Windows
To find a symbol with Character Map:
- Press the Windows key.
- Type charmap.
- Open Character Map.
- Select a checkmark character.
- Copy it and paste it into the PDF.
Microsoft Word also includes a More Symbols menu. However, avoid relying on Wingdings where possible. Font-dependent symbols may not display consistently in every PDF viewer, while standard Unicode symbols are generally more reliable.
Use Character Viewer on macOS
On a Mac, press Control + Command + Space or open Edit > Emoji & Symbols from the menu bar in a supported app.
Search for “checkmark,” choose the preferred symbol, and paste it into the pdfFiller text box. Review the exported PDF to confirm that the special character displays correctly.
Can you add marks to a scanned PDF?
Yes. Checkmarks, circles, crosses, signatures, and text boxes can generally be placed over scanned PDF pages as annotations.
A scanned PDF often consists of page images rather than editable text and interactive form fields. You may not be able to click into an existing printed field, but you can still:
- Add checkmarks
- Place circles and crosses
- Insert text boxes
- Add comments
- Use a sign feature
- Mark areas for review
Adding an annotation does not automatically convert scanned content into editable text. A separate text-recognition or document-conversion workflow may be required for that.
How to add PDF marks on a phone or tablet
You can add marks from a mobile device through a supported browser or the pdfFiller app for iOS or Android.
Open or upload the PDF, select the required mark tool, and tap the desired location. For better accuracy:
- Zoom in before placing small marks
- Use a stylus when available
- Review alignment before saving
- Reopen the downloaded file
Some mobile devices also provide built-in PDF or Markup tools that allow users to draw or paste checkmark symbols. Available features depend on the device, operating system, and app. For more information about editing PDFs on your mobile devices, see our blog: How to edit a PDF on your phone.
Alternative ways to add a checkmark to a PDF
Many free and paid tools can place checkmarks in PDF files. Available features, account requirements, file limits, and pricing may change, so check the current product terms before choosing a workflow.
Microsoft Edge
Microsoft Edge provides built-in tools for viewing and annotating PDFs without extra software. Depending on the browser version, you may be able to draw, add text, or paste a symbol such as ✓.
The available method can differ for fillable and static PDFs.
Adobe Acrobat
Adobe Acrobat includes form-filling, commenting, text, and signing features. Depending on the version, users may be able to insert a checkmark through Fill & Sign, form tools, or annotation features.
Some advanced functions may require a paid Acrobat plan.
PDFgear, Smallpdf, and DocHub
PDFgear, Smallpdf, and DocHub provide PDF editing or annotation tools that may support checkmarks, text symbols, shapes, or form filling.
Some workflows may be available without installation, but sign-up requirements and free-use limits vary. Avoid assuming that every feature is entirely free or unrestricted.
Foxit PDF Editor
Foxit PDF Editor includes text, annotation, and form tools. In some versions, a Typewriter or text feature can be used to insert a checkmark character.
Feature availability depends on the product version and plan.
Preview on Mac
Preview includes built-in Markup tools for adding shapes, text, and drawings to PDFs on macOS. It can be suitable for basic annotations without additional software.
Microsoft Word
Some PDFs can be opened in Microsoft Word or MS Word, edited, and exported as a new PDF. However, conversion may alter page breaks, fonts, spacing, images, and form fields.
When only a few marks are needed, editing the original PDF directly is generally less likely to affect the layout.
Common mistakes when adding marks to PDF files
Adding shapes to a PDF document may seem straightforward, but there are a few common pitfalls to watch out for.
Using a static mark instead of a fillable field
A visible checkmark is not clickable. Use interactive check boxes when other people need to complete the form.
Placing marks outside the intended field
Zoom in before marking small boxes. A misplaced tick or cross can make a response unclear.
Covering important content
A circle or cross should not obscure text, numbers, or nearby fields.
Using an unsupported symbol font
Wingdings and other font-dependent characters may display differently after export. Use standard Unicode special characters when possible.
Editing the wrong version
Confirm the filename before uploading, especially when several versions are stored on your computer or in cloud storage.
Failing to review the download
Open the saved file before sending it. Marks and text can sometimes appear differently in another PDF viewer.
Sharing sensitive files insecurely
Use an appropriate delivery method for files containing personal, financial, medical, or business information. Do not assume that every service automatically stores documents in encrypted folders or provides the same security controls.
How to keep PDF marks clear and consistent
Use the same mark size where possible and align checkmarks or crosses inside the relevant fields.
Circles should frame content rather than cover it. Checkmarks and crosses should remain visually distinct so there is no uncertainty about the intended response.
When using text-based symbols, prefer Unicode characters over font-dependent alternatives. Reopen the exported PDF and verify that all annotations, signatures, and fillable fields display correctly before sharing it. See our guides to recall pdfFiller’s functionality on PDF annotation, adding signatures to PDFs, and sharing and collaborating on PDFs in real time.
