Image CompressorCompress JPG, PNG and WebP images in your browser by quality or to a target size such as 100 KB.
Compress PDF
Two honest methods: “Lossless” rebuilds the file with compact object streams and drops unused data, keeping text selectable; savings are often modest. “Strong (rasterize)” turns every page into a JPEG image, which can shrink scans a lot but makes text unselectable and unsearchable.

Strong mode makes text unselectable and removes links. Keep your original file.

Examples
Scanned contract, 18 MB
Strong mode at 120 DPI and quality 70% typically produces a much smaller file that is still readable on screen.

Check it yourself: open your browser’s developer tools, select the Network tab and use the tool. Your file never appears in an upload request. Once this page is saved for offline use, you can also disconnect from the internet and keep working. Ads and anonymous visit statistics, when enabled, make their own requests, but they never receive your files or text.
Frequently asked questions
Why is the lossless saving small?
Most of a PDF’s size is usually images and fonts. Recompressing embedded images without rasterizing pages requires deep PDF rewriting that this browser tool does not perform.
What does rasterize mean for me?
Each page becomes a picture. Text can no longer be selected, searched or read by screen readers, links stop working and printing quality depends on the DPI you pick. Keep the original.
Is there a page limit?
Strong mode renders pages one by one; documents of a few hundred pages work on desktop but may be slow on phones.
