Rewrite the text already in a PDF, or add text, images, shapes, ink and links, entirely in your browser. Free, unlimited, and never watermarked.
Edit a PDF without uploading the document, creating an account, accepting a daily task counter, or receiving a watermark. FileGizmo runs the editing workflow on this device and creates a new PDF copy for download. Your original file remains unchanged.
Text already in the document can be rewritten. Choose Edit text, click the words you want to change, and retype them. The replacement keeps the original size, family, weight and slant, and the patch behind it takes its colour from the page rather than assuming white, so a correction on a tinted row leaves no pale rectangle. Find and replace does the same across every page at once.
Two limits matter. It needs a real text layer, so a scanned page will not respond; that is a picture of text, and Local OCR is the tool for it. And the original is painted over rather than rewritten in the content stream, so by default it stays in the file and can still be copied out even though the page no longer shows it. The editor says so the moment you replace anything, and offers a way out: tick the box in that warning and the corrected pages export as pictures, removing the old words for good at the cost of those pages no longer being searchable.
Beyond changing existing words, the editor adds new content. You can place a text box and choose a standard PDF font, size, colour, alignment, bold, or italic styling. You can add a PNG or JPG, draw freehand ink, create rectangles, ellipses, lines, and arrows, and mark regions with highlight, underline, or strikethrough graphics. Link areas create clickable web links. Every item can be moved, resized, rotated, undone, redone, or applied to all pages.
Changing existing text works by covering, not by rewriting the PDF’s internal text. Rewriting that content stream would need the original embedded font, character map, shaping rules, and exact layout, and a tool that guesses can break spacing or substitute the wrong glyphs. So Edit text paints over the old words and draws the new ones on top, and the editor says plainly that the old words remain in the file until those pages are exported as images. When confidential text has to go, use Redact PDF, which removes it from the file.
Region highlighting works the same way. You draw a translucent rectangle over the area you want to mark; the editor does not pretend it selected semantic text when it did not. Underline and strikethrough marks are also positioned regions. This approach works on scanned pages and ordinary PDFs alike, while keeping placement predictable.
Edits are written with vector PDF operations wherever possible. Text remains text, shapes remain vector graphics, and untouched pages are not rasterized. An uploaded image or freehand drawing is embedded only as its own image object. That preserves the quality and searchability of the rest of the document.
Your edit state is autosaved to IndexedDB on this device with a file fingerprint, not silent source-file storage. If the tab closes unexpectedly, return to the editor, choose Restore, and reselect the same file. FileGizmo verifies the fingerprint before reapplying your objects. Saved work expires after seven days and can be cleared at any time.
Before sharing the result, open the downloaded PDF in a separate reader. Check every modified page, test each link, confirm that cover blocks do not hide something unintentionally, and keep the untouched original. If a document contains an existing cryptographic signature, remember that any edit can invalidate that signature’s assurance.

Export and download the edited PDF
Click any text the PDF was made with and retype it, or find and replace a phrase across every page at once. The replacement keeps the original size, family, weight and slant, and the patch behind it takes its colour from the page rather than assuming white.
Place styled text, PNG or JPG images, vector shapes, freehand drawings, highlights, underlines, strike marks, links, and cover blocks, on real page previews with drag handles, rotation, keyboard nudging, undo and redo.
New text and shapes are written into the PDF without flattening the page into an image, so untouched content keeps its original quality and stays searchable.
Processing runs on this device. Open the browser’s Network panel while the tool works and you will see no file upload request to FileGizmo. Temporary previews use local browser URLs, and closing or resetting the page releases them instead of leaving a server copy behind.
Use the tool without a daily task counter, account wall, output watermark, or artificial upload cap. FileGizmo does not meter a transfer it never receives. Available memory, processor speed, browser canvas limits, and the file format itself set the practical limit.
Use a current browser on desktop, Android, iPhone, or iPad without installing an app. Once this tool and its required assets load, the cached workflow works without a connection. Large jobs are usually more comfortable on a desktop with additional memory.
Yes. FileGizmo has no daily task counter, account wall, or output watermark. Practical limits come from your device memory and browser, not an artificial quota.
No. The PDF is read, previewed, edited, and exported in your browser. The document is not sent to a FileGizmo processing server.
Yes. Choose Edit text and click the words you want to change. The replacement matches the original size, family, weight and slant. It needs a real text layer, so a scan will not respond. The original is painted over rather than rewritten, so it remains in the file unless you tick the box in the warning to export those pages as pictures.
No. Cover hides content without destroying it, so the words underneath can still be searched or copied. The exception is text replaced with Edit text, where ticking "remove the replaced wording" on export re-renders those pages as pictures. For anything else that must be destroyed, use Redact PDF, which removes the marked text from the file. Cover is for tidying, not for secrets.
Yes. Page thumbnails, touch-friendly controls, pinch zoom, and local autosave are included. Very large documents may be more comfortable on a device with more memory.
