Compress PDF to 500 KB

Aim for a 500 KB PDF — ideal for multi-page documents and detailed scans.

Temporarily unavailable

A program this tool depends on isn't available on the server right now, so it can't run. Other tools may still work — try the tool directory.

This page opens the PDF compressor pre-aimed at 500 KB. A 500 KB limit suits longer or image-heavy PDFs that still need to upload quickly. Drop your file and the tool searches the image-quality ladder for the highest quality whose output still fits 500 KB; if the target is too tight for a given document, it hands back the smallest version it could make and shows the exact size it reached — no silent failures and no fake promises.

You can change the target at any time, or set a different size per file. Text stays sharp because only the embedded images are re-encoded. Files are processed privately and deleted right after.

Frequently asked questions

Can every PDF really reach 500 KB?
Not always. A short, text-based PDF usually gets well under 500 KB; a multi-page colour scan may not, because readable scanned images have a size floor. When the target can't be met, we return the smallest good result and tell you its size, so you can decide whether to lower the maximum image dimension or accept it.
What if I need a different size than 500 KB?
Just type a new number in the Target size box, or pick one of the quick-size chips. The tool re-aims instantly — you don't need this specific page.
Does hitting the target wreck quality?
We always keep the highest quality that still fits, rather than crushing the file blindly. For tight targets on image-heavy PDFs some softening is unavoidable, but text and layout are preserved.
Is it safe and private?
Your file is uploaded over HTTPS, processed on our server, and the upload is removed right after. The generated result is cleaned up automatically by a periodic job. We never share your files and no account is needed. See our Privacy Policy.
