General Questions
What is the PDF Editor?
The PDF Editor is a browser-based tool in Appfactory Studio for editing PDF documents. You can add text, images, signatures, shapes, manage pages, and more — all directly in your browser without downloading additional software.
Is it free to use?
PDF editing is included with your Appfactory Studio account. Check your account plan for usage limits.
Do I need to install anything?
No. The PDF Editor runs completely in your browser. No software installation is required.
Is my document secure?
Yes. Documents are stored on secure Appfactory servers with encryption. Only you and people you explicitly share with can access your documents.
What file formats are supported?
Upload: PDF files only Export: PDF files only
You cannot import or export Word (.docx), Excel (.xlsx), or other formats directly. You can:
- Convert documents to PDF using other tools first
- Export as PDF and open in other applications after
Features and Capabilities
Can I edit text in existing PDFs?
Yes. When you open a PDF, all extractable text appears as editable elements. You can:
- Modify text content
- Change formatting (font, size, color, etc.)
- Move or resize text boxes
- Delete text elements
Can I add text to a blank document?
Yes. Create a new blank document and use the Text tool to add content.
Can I insert images?
Yes. Use the Image tool to insert PNG or JPEG images. You can:
- Resize images
- Move them around
- Reorder pages with images
Can I draw freehand?
Freehand drawing is supported via the Signature tool's draw mode. For other freehand drawing, use shapes (rectangles, ellipses) or add pre-drawn images.
Can I add signatures to documents?
Yes. Use the Signature tool to:
- Draw a signature with your mouse/touchpad
- Type your name in a signature font
- The signature is stored and reused
Can I merge multiple PDFs?
Not directly in the editor. However, you can:
- Open PDF 1
- Add pages from PDF 2 using duplicate + manual work
- Or copy pages from PDF 2 and manually recreate
Workaround — Use a dedicated PDF merger tool first, then edit in the PDF Editor.
Can I split a PDF?
Not directly. You can:
- Open the PDF
- Delete unwanted pages
- Export as a new PDF
This effectively creates a split document.
Editing Problems
Text editing seems unresponsive
Problem — Text doesn't appear when I type or edits are slow Solution:
- Try double-clicking the text again to re-enter edit mode
- Clear browser cache and refresh
- Try a different browser
- Check your internet connection
Why — Temporary browser glitch or network issue
Can't select or move elements
Problem — Elements won't select when I click them Solution:
- Make sure text is not in edit mode (press Escape first)
- Click directly on the element, not just near it
- Try clicking with a different mouse button (to check it's not a hold mode)
- Refresh the page and try again
Why — Focus is locked on another element
Undo doesn't work
Problem — Ctrl+Z isn't undoing my changes Solution:
- Check you're using Ctrl+Z (or Cmd+Z on Mac)
- Try clicking the Undo button in toolbar
- Refresh and check if undo history is preserved
- You may have exceeded undo limit (200 steps)
Why — Undo history limit reached or focus lost
Zoom doesn't work properly
Problem — Zoom slider doesn't respond or zooms incorrectly Solution:
- Try using browser zoom (Ctrl+Plus to zoom in)
- Use the zoom percentage in the toolbar
- Refresh page if zoom is stuck
- Test in a different browser
Why — Browser rendering issue
Saving and Export
Are changes saved automatically?
Yes, but only after you've manually saved at least once. Then:
- Every 15 seconds, autosave creates a version
- You can see autosave status indicator
- Versions are available in History
How do I manually save?
Click the Save button in the toolbar or press Ctrl+S (Cmd+S on Mac).
Can I save as I go?
Yes. You can save as frequently as you want. Each save creates a new version.
What happens if I close without saving?
If you haven't manually saved yet:
- Your work is lost
- Always save before closing
If you have autosave enabled (after first save):
- Recent autosaves are available in History
- You can restore from autosave version
Document won't save
Problem — Save button doesn't work or save fails Solution:
- Check your internet connection
- Verify you have permission to edit (not View Only)
- Refresh the page and try saving again
- Check browser console for error messages (F12)
- Try a different browser
Why — Network issue, permissions problem, or browser compatibility
Can I export as a different format?
Not currently. The PDF Editor only exports as PDF. To convert:
- Export as PDF
- Use a third-party converter (PDF to Word, etc.)
- Or import from other formats by converting to PDF first
File size is too large
Problem — Exported PDF is much larger than expected Solution:
- Delete unnecessary images
- Remove extra pages
- Reduce image resolution if possible
- Save and export again
Why — Large images, many pages, or high resolution
Exported PDF looks different
Problem — PDF doesn't match what I see in editor Solution:
- Check zoom level (it affects appearance)
- Verify all edits were saved before export
- Try zooming to 100% before exporting
- Check if fonts match (use standard fonts)
- Refresh and try exporting again
Why — Rendering differences, unsaved changes, or font issues
Sharing and Collaboration
Can I share documents with others?
Yes. Click the Share button and:
- Share with specific team members by email
- Generate a link for anyone with access
- Set View Only or Edit permissions
Can I revoke access?
Yes. In the Share dialog:
- Find the person or link
- Click the X or "Remove Access"
- Access is revoked immediately
Invitation wasn't received
Solution:
- Check spam folder for invitation email
- Verify email address is correct
- Ask recipient to check their email
- Try sharing the generated link instead
Can I share with people outside my organization?
Currently, no. Sharing only works within your Appfactory organization. To share externally:
- Export document as PDF
- Share the PDF file directly
- They can download and view
Real-time collaboration not working
Problem — Other person's changes aren't showing up Solution:
- Press F5 to refresh the page
- Wait a moment (autosave is 15-second intervals)
- Ask other person to save
- Refresh again to see their changes
Why — Need to manually refresh to see others' changes
OCR and Scanning
Why isn't OCR working?
Problem — OCR button doesn't do anything Solution:
- Text may already be searchable (try Ctrl+F first)
- Refresh the page and try OCR again
- Check internet connection (OCR downloads Tesseract.js)
- Wait longer (first run takes 5-15 seconds)
- Try on a different browser
Why — Already searchable, network issue, or browser compatibility
OCR results are very inaccurate
Problem — Recognized text has many errors Solution:
- Double-click text to correct individual errors
- Manually add correct text using Text tool
- Delete incorrect OCR text
- Use higher-quality scans in the future
Why — Low scan quality, small text, or unusual fonts
OCR is too slow
Problem — OCR takes many seconds to complete Solution:
- First run takes longer (it downloads ~5MB)
- Subsequent runs are faster (use cached version)
- Close other browser tabs to free resources
- Wait for completion, don't interrupt
Why — First run downloads processing library
Scanned document looks blurry after OCR
Problem — Text and images appear fuzzy in editor Solution:
- This is normal for scanned PDFs
- Zoom in to 100-150% to see better
- OCR text is invisible but searchable
- The original scan appearance is preserved
- Exported PDF will match what you see
Why — Scanning produces lower resolution images
