Frequently asked questions
Is my PDF uploaded to a server to compress it?
No. Compression runs entirely in your browser, so the file never leaves your device. That makes it safe for contracts, statements and other confidential PDFs.
Why did my PDF barely shrink?
PDFs that are mostly text or vector graphics are already well-compressed, so there is little to remove. This tool saves the most on image-heavy PDFs like scans and photo-filled documents.
Will compressing reduce the quality?
The tool recompresses streams, images and fonts and removes unused objects to cut size. Text and vector content stays sharp; heavily image-based pages may be re-encoded to save space.
Does the compress PDF tool work offline?
Yes. GoodWebTools is a PWA, so once the page has loaded it keeps compressing PDFs with no internet connection.
