1Upload the PDF documents you want to work on; the file opens on an editable canvas in your browser with nothing installed.
2Crop, rotate, resize, draw, add text and shapes, or adjust colour — every change lands on a working copy, never on your upload.

4Export back to PDF, or to a lossless format instead if you are still part-way through editing.
PDF Editor FAQ
Anything specific to PDF in the editor?
+
Yes — a PDF is an object graph, not a page image, so text stays selectable and vectors stay sharp no matter what happens to the raster content inside it. Worth knowing before you export over your only copy.
Is my file uploaded, or does editing happen locally?
+
Editing happens in your browser; the file goes to our workers only for the operations that genuinely need server-side processing, and it is deleted shortly afterwards.
How does PDF Editor let me edit without installing anything?
+
Concretely, the file is decoded into an editable canvas in the browser and your changes are composited once at export. The editing surface is the browser, so there is nothing to install and no licence to hold.
What can I actually change?
+
Crop, rotate, flip, resize, draw, add text and shapes, and apply filters and colour adjustments. Everything is applied to a working copy, so the file you uploaded is never modified in place.
Does PDF Editor cost anything?
+
No. PDF Editor is free without an account, and nothing is stamped onto the pages. Uploaded documents are deleted from the workers shortly after the job completes.
What can I upload to PDF Editor?
+
Any standard PDF, including ones produced by a scanner, by a word processor or by a print driver. Files with an owner password that only restricts editing are handled; files that need a user password to open are not, and we do not attempt to break encryption.
Is there a file size limit on PDF Editor?
+
Yes: free accounts process documents up to 25 MB each, which covers most reports and contracts but not a long scanned document at 600 DPI; Ghostscript and qpdf do the work. Scanned PDFs are the usual thing that exceeds it, and compressing the document first is normally enough to bring it back under.
Do bookmarks, links and form fields survive?
+
Outlines, internal links and annotations are preserved wherever the operation allows it. Digital signatures are the exception: any change to the file necessarily invalidates a signature, because that is precisely what a signature is for.
Why does a MP3 site host PDF Editor?
+
MP3.to is built around the format that made portable audio ordinary: universally playable, small enough to ignore, and lossy in a way that only matters if you keep re-encoding it. Audio jobs cluster: the same person who needs a format changed usually needs the file cut, levelled or made smaller in the same sitting. Putting PDF Editor behind the same upload, the same caps and the same account is what turns three tabs into one.
What should I do with the result once PDF Editor is finished?
+
The converter on this site moves audio between MP3, WAV, FLAC, M4A, OGG and Opus, so the output format is a decision you can leave until the end rather than commit to at the start. Doing that after PDF Editor rather than before means the encode happens once, on the file you actually settled on, instead of twice.
Is PDF Editor here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build, the same workers, the same limits. What a MP3 site adds is a point of view about bitrates, about what survives an encode and about when a lossless intermediate is worth the upload time. It also starts from one fact about the format this site is named after: MP3 frames are fixed-size blocks, so a cut lands on a frame boundary and gapless playback markers do not survive a re-encode.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is listened to and nothing is indexed. Free accounts exist for history and batch size, not for access.
