À propos de cet outil

This PDF compressor runs entirely in your browser. Your file never leaves your device, so contracts, IDs and personal documents stay private. It shrinks file size the same way professional tools do: oversized scans are downsampled to a page-aware DPI, then images are re-encoded with MozJPEG. Text stays as real characters, so pages stay sharp, selectable and searchable. Scanned and image-heavy PDFs often save 94% or more. Text-only files usually change far less, because there was little image data to reclaim. Files up to 10 MB are supported. Pick Light, Balanced or Strong, compress, then download a smaller copy. The original on your device is never overwritten.

Pourquoi l’utiliser

  • Scanned and image-heavy PDFs often shrink by 94% or more with Strong compression, without turning pages into blurry pictures.
  • Runs 100% in your browser. Nothing is uploaded to a server.
  • Text stays sharp, selectable and searchable. Pages are not flattened into blurry images.
  • Page count, order and content stay the same. Only embedded images are recompressed.
  • Free to use with no account, no watermark and no daily cap.
  • Accepts PDFs up to 10 MB, which covers most email attachments and form uploads.

Usages courants

  • Shrinking a scanned contract or ID so it fits an email attachment limit.
  • Meeting a portal upload cap for visas, universities or job applications.
  • Reducing a report full of photos before sending it to a client.
  • Compressing receipts and invoices before an expense claim.
  • Making a large PDF practical to share on a slow or metered connection.

Conseils pour de meilleurs résultats

  • Use Strong for scans and photo-heavy PDFs when you need the biggest size drop, often 94%+.
  • Use Light or Balanced when the PDF must stay close to print quality.
  • Keep files under 10 MB. If yours is larger, split it first or remove unused pages.
  • Compress once at the end. Running the same file through Strong repeatedly can soften images without much extra saving.
  • For strict upload limits, try Strong first, then split or remove pages if the file is still too large.

Erreurs à éviter

  • Expecting a text-only PDF to shrink by 94%. Most of the size in those files is already efficient.
  • Uploading a file over 10 MB. The tool rejects anything larger.
  • Assuming compression removes pages. It does not. Only image encoding changes.
  • Trying a password-protected PDF first. Unlock it with the PDF Unlocker, then compress.
  • Compressing the same file over and over hoping for more savings. After the first Strong pass there is usually little left to reclaim.

No. Text stays as real characters and fonts, so it remains sharp, selectable and searchable. Only embedded images are recompressed.

Image-heavy and scanned PDFs often save 94% or more with Strong. A text-only document may barely change, because there was little large image data to compress.

Usually because it is mostly text, or its images were already well compressed. This tool reclaims space from inefficient images. If there are none, there is little to save.

There is no exact KB target mode. Use Strong compression and check the downloaded size. If it is still too large, split the PDF or remove pages you do not need, then compress again.

No. Every page stays, in the same order, with the same content. Only how embedded images are stored changes.

Not directly. Unlock it first with the PDF Unlocker if you know the password, then compress the unlocked file.

Yes, if the original had a real text layer. Compression does not turn text into pictures. A scan that was never searchable still needs OCR.
