Big PDF that won't attach to an email? Compress it here for free. Pick a compression level and you'll see the estimated output size before you commit, so you can shrink the file as much as you need while keeping it readable.
The whole process runs in your browser — your document is never uploaded — and there are no watermarks. For image-heavy and scanned PDFs the savings can be dramatic; text-only PDFs are often already small.
Choose the 'best quality' level, which reduces file size while keeping pages sharp. You can preview the estimated size of each level before downloading.
Text-only PDFs are often already optimised, so there's little to remove. The tool keeps the original if compressing wouldn't make it smaller. The biggest savings come from scanned or image-heavy PDFs.
No — compression runs entirely in your browser, so your PDF never leaves your device.
