FAQ
Most image-based PDFs (scans, photo composites) can. Text-only PDFs are already tiny — if the file is under 1MB it is returned unchanged and your quota is not consumed.
Try it ↑1MB is a generous target for documents up to ~10 pages, so sharpness is usually unaffected; for very long files consider splitting first.
Try it ↑Same engine — the target is simply preset to 1MB so you skip the typing. You can change it to 200KB, 500KB or anything else at any time.
Try it ↑No — compression runs entirely in your browser.
Try it ↑No. Any change to a signed PDF (merging, compressing, watermarking…) invalidates the existing digital signature — that is the tamper-proof design of PDF signatures, not a limit of this site. Process first, then sign.
Try it ↑Yes — and you can verify it: the tool runs on open-source in-browser engines (pdf-lib, pdf.js, Tesseract OCR…) on your own device. Open DevTools → Network while processing and you will see no file upload requests.
