What you can do with the FlexFiles PDF Editor
The FlexFiles PDF Editor runs entirely in your browser and handles the full range of edits professionals need day-to-day. You can add new text anywhere on a page, or click into existing text to change it in place — no covering up the original with a white box. Insert images (JPG, PNG, SVG), draw signatures by hand, type a signature, or upload a photo of one. Use the highlight, underline, strikethrough, and shape tools to annotate without altering the underlying content. Rotate, reorder, or delete individual pages, and merge several PDFs into a single document before exporting.
Every page you do not touch is carried through unchanged — text stays selectable and images keep their original resolution. There are no watermarks on exported files, and no daily conversion limit for the free editing tools.
How to edit a PDF online
- Open your PDF. Drag a PDF into the editor or pick one from your device. The file opens in the browser - nothing is installed and no account is needed to start.
- Edit the page. Add or change text, insert images and signatures, draw shapes, highlight passages, and crop or rotate pages. Existing text is detected so you can edit it in place rather than covering it up.
- Arrange and combine. Reorder, rotate or delete pages, and merge several PDFs into a single document before exporting.
- Export. Save the finished document back to PDF, or export it in another supported format.
PDF Editor FAQs
Do I need to install anything or create an account?
No. The editor runs in your browser, and you can open a PDF and start editing without signing up. An account is only needed for features that save work to a workspace.
Can I edit text that is already in the PDF?
Yes. Existing text is detected and split into editable elements, so you can change wording in place while keeping the surrounding layout and background intact.
Can I sign a PDF?
Yes. You can draw a signature, type one, or insert an image of one, then position it anywhere on the page before exporting.
Does editing change the quality of my document?
No. Pages you do not touch are carried through unchanged, so text stays selectable and images keep their original resolution.
Is my file private?
Files are processed for your session and are not shared. See the privacy policy for how uploads are handled and retained.
Can I add images or logos to a PDF?
Yes. You can insert any image file — JPG, PNG, SVG — and resize, reposition, or rotate it on the page before saving.
Can I merge multiple PDFs together?
Yes. You can combine several PDF files into a single document inside the editor, or use the dedicated Merge PDF tool if you only need to join files without editing them.
What file formats can I export to?
You can save your work as a PDF. If you need other formats — Word, Excel, JPG — use the conversion tools linked in the Related tools section below after downloading your edited PDF.
Can I highlight or annotate text in a PDF?
Yes. The editor includes highlight, underline, and strikethrough tools for existing text, plus drawing and shape tools for adding annotations anywhere on the page.
Is the FlexFiles PDF Editor free?
Yes, all core editing features — text editing, annotations, signatures, image insertion, page rotation, and export — are free with no daily limit or watermark. Advanced workspace and collaboration features require a FlexFiles Pro plan.
