When you would use this

Situations, not settings.

A page with fine lines or small text
PNG is lossless, so a circuit diagram or a table of figures keeps its edges instead of picking up JPG mush around the strokes.
You need a transparent background
A JPG has to fill the background with white. PNG can leave it clear, which matters when the page goes on top of something else.
Artwork headed into a design tool
Figma and Canva both take PNG directly, and a lossless import means the next export is not compressing something already compressed.

How it works / no cloud

A conversion engine, not an upload form.

filetity renders each page in browser memory and writes it as PNG, which stores every pixel exactly. You can keep the page background transparent, which is something JPG cannot do at all. Nothing is uploaded.

Straight answers

No accordion. Nothing hidden.

Is it free?
Yes, with no watermark and no page limit.
Does it need an account?
No. There is no account system.
Is my file processed on my device?
Yes. The file is read by your browser and never uploaded. There is no server to send it to.
What formats are supported?
PDF in. PNG out, one image per page. A single page downloads on its own, several arrive as a ZIP. Backgrounds can be white or transparent.
What are the limits?
No page limit. PNG files are considerably larger than JPG, so a long document at 300 DPI can run to hundreds of megabytes.
Does it work on mobile?
Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
Does it work offline?
Yes, after you have used it once. Your browser keeps what the tool needs, so it then works with no network connection.
Should I use PNG or JPG for this?
PNG for anything with text, diagrams, charts or line art, because it keeps hard edges exactly. JPG for pages that are mostly photographs, because the file will be a fraction of the size and you will not see the difference. If you are unsure and the page has any text on it, use PNG.
Can I get a transparent background?
Yes, and it is the main reason to choose PNG here. Set the background to transparent in the settings and anything the page leaves blank stays see-through, so a logo or diagram can be dropped straight onto another design. JPG has no transparency channel, so it cannot do this at any quality.
Why are the files so much bigger than JPG?
Because PNG is lossless. It stores every pixel exactly instead of approximating, so nothing softens and nothing gets halos, and the file is several times larger. That is the trade you are making deliberately.
Can I convert some pages and not others?
Yes. The range box takes 1-5, 8 style input and only those pages are drawn. Leave it empty for every page. If what you typed makes no sense to the tool, it falls back to every page rather than producing nothing.
Why does the conversion fail on a large page?
Canvas memory. A page rendered at 300 DPI is a bitmap of millions of pixels, and PNG keeps every one of them, so a poster-sized page can exceed what the browser will hold. Drop to 150 DPI and try again, which is what the failure message suggests.
