SellstampCompress PDF
Make a PDF smaller by re-compressing the photos inside it, in your browser. You see the size before and after, and if it cannot get smaller you keep your original.
Choose or drop a PDF. It is opened in this tab and never uploaded.
Your file stays on your device
Your browser opens and processes the file itself. It is never uploaded, to Sellstamp or anyone else, and nothing is kept after you close the page.

How to use it
- Choose the PDF.
- Pick how much: a little (print quality), balanced, or most (screen only).
- Press “Compress the PDF”.
- Check the before and after sizes, and download it.
Your files are not uploaded
The PDF is put together by this browser tab. Your files are read from your device, processed here, and the result is handed back to you as a download. Nothing is sent to Sellstamp or anyone else, so there is no copy on a server to worry about afterwards, and no upload to wait for.
What a browser can compress, honestly
The photos inside a PDF (JPEG images) are usually most of its size. This tool shrinks each one to at most 3,000, 2,000 or 1,200 pixels on its longest side and re-saves it at a lower JPEG quality, keeping the new version only if it is smaller. Text, vector drawings and fonts are left exactly as they were, so text stays sharp and selectable.
When it barely helps
A PDF that is mostly text, fonts or non-photo images will not shrink much here; server tools that rebuild fonts can do more, but they need your file. CMYK images (common in print-ready files) are left alone, because converting them in a browser shifts their colours. You always see the result before you download.
Questions
How much smaller will my PDF get?
It depends on how much of it is photos. A PDF of scans or photos can shrink a lot; a text document may barely change. The page shows the before and after sizes.
Will text become blurry?
No. Only photos are re-compressed; text and vector graphics are untouched.
Which level should I pick?
“A little” for printing, “Balanced” for email and sharing, “Most” for reading on a screen only.
Why is my PDF not smaller?
It has no JPEG photos to re-compress, or they were already compressed tightly. Your original is offered unchanged rather than a bigger copy.
Is my file uploaded to be compressed?
No. Compression runs in your browser, which is why it can only do what a browser can do.
