No signup

The free workflow starts in the browser and does not require an account before file export.

Ad-safe

Downloads are not gated behind ad interactions or ad impressions. Ads remain disabled until policy review and search visibility are ready.

Use the strictest PDF target

Open the PDF compressor with the 100KB target selected. This is a severe limit and works best for one short scanned page or a simple form.

Expect quality tradeoffs

A 100KB PDF cap can blur stamps, signatures, and small text. Keep the original and inspect the compressed copy before submitting it.

If it still fails

Split the PDF to the required page, reduce source image dimensions, or convert the page to an image before rebuilding a smaller upload file.
