Compress PDF to a Target Size
Pick a size, add your PDF and CometBits reduces it to fit. It works by turning each page into a compressed picture, which gives a much smaller file but means the text is no longer selectable. That is usually fine for forms and uploads. Your file never leaves your device.

Questions
Will the text still be selectable?
No. To reach small sizes, each page is converted to a compressed image. This works well for forms, scans and uploads, but if you need searchable text, keep the original too.
What if my PDF can not reach the target?
Very long PDFs or tiny targets can make pages blurry. We pick the best quality that fits and warn you if the result looks too soft. Try a larger target or split the file.
How long does it take?
Most PDFs take a few seconds. A scan of 30 or more pages can take up to a minute on an older phone. The progress bar shows how far along it is.
Is my document uploaded?
No. All of the work is done by your browser on your own device.
