PDF Editor FAQ
Does the file format limit what the editor can do?
+
It does. PDF fixes the page: fonts, vectors, raster images and text coordinates are frozen so every reader sees identical layout. What the format can represent bounds what any editor can preserve, here or on the desktop.
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 anything lost when I export?
+
Only what the export format cannot represent. Choose a lossless output while you are still iterating and a compressed one when you are finished — exporting to a lossy format between edit sessions is what accumulates damage.
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.
Can I run PDF Editor on several PDF documents at once?
+
Yes — upload the set and they process in parallel under one set of settings, which is the point of doing a document workflow here rather than clicking through a desktop reader.
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.
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.
Is there a file size limit on PDF Editor?
+
Yes: free accounts process documents up to 5 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.
Why does a PNG site host PDF Editor?
+
PNG.to is built around the format you use when you cannot afford to lose a pixel: lossless, alpha-capable, and the correct answer for screenshots, logos, line art and anything with hard edges. Image work is rarely one step: people arrive to change a format and leave needing the picture a different size, a different weight or a different shape. Running PDF Editor on the same upload pipeline, the same size caps and the same account is the whole reason it is here rather than on a fourth tab.
What should I do with the result once PDF Editor is finished?
+
The converter on this site moves images to and from PNG, JPG, WebP, GIF and SVG — which is the step where the decision about transparency actually gets made. That is the step most people actually came for, and doing it after PDF Editor rather than before it means the conversion works from the file you finally settled on.
Is PDF Editor here the same tool the sibling sites run?
+
The engines are shared — the same libraries, the same workers, the same limits. What differs is the advice, and the advice here starts from one fact about the format this site is named after: there is no quality slider to get wrong — a PNG round-trips bit-exactly, so the only thing edits cost you is file size. A PNG site is opinionated about where PNG is the right destination and where it is not, and that judgement is worth more than the button.
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, and nothing you process is indexed, listed or used for anything else. Free accounts exist for history and batch size, not for access.
