Files are processed in your browser and never uploaded.

University application portals, recruitment systems, and many government uploads allow files up to 1MB. This tool reduces your PDF to fit under 1MB while keeping high readability, because a 1MB budget leaves room for good image quality. Compression happens locally in your browser — nothing is uploaded. A 1MB limit is the most forgiving of the common caps, so multi-page transcripts, certificates, and portfolios usually stay close to their original sharpness while still slipping under the threshold. It is also handy when an email provider or web form rejects attachments larger than one megabyte, letting you send the document without splitting it apart. As with every tool here, there is no registration, no install, no usage cap, and no watermark, and your file is processed entirely on your own device for full privacy.

How it works

  2. Compress in-browser

    We lower image resolution and quality until it hits the target size.

FAQ

Is 1MB enough for a clear scanned document?

Usually yes. 1MB allows much higher quality than smaller targets, so scans remain crisp.

Will it work for a PDF that is mostly text?

Text-only PDFs are already small and may not shrink much; the tool will tell you the smallest achievable size.

Do you store my file?

No. Everything runs in your browser; your file is never sent to a server.
