Compress a drawing set to email or upload
Email and project portals often cap file size. Scanned sheets, as-builts and site photo reports shrink the most. Plan sheets drawn in CAD are mostly lines and text, so they shrink less, but they stay sharp.

Questions
How much smaller will it get?
Files full of photos or scans shrink the most. Drawings made of lines and text are already small, so they shrink less.
Will it look worse?
Light keeps photos close to the original. Strong makes photos softer to save the most space. Lines and text stay sharp at every setting.
Are my files uploaded?
No. The tool runs in your browser, so your files never leave your device. Nothing is sent to us or kept after you close the tab.
Is it free?
Yes. There is no sign-up, no watermark on your file and no daily limit.
Does it work offline?
Yes. Once the page has loaded you can turn off Wi-Fi and the tool still works.
