Compress a PDF to 1 MB.

For email attachments and upload caps. The target is pre-set to 1 MB — adjust to anything. Compressed on your device; the file is never uploaded.

Open your network tab while it runs: zero requests. Your document stays yours.

How the 1 MB target works

  1. Select the PDF — already under 1 MB? We return it unchanged instead of degrading it pointlessly.
  2. Progressive compression — quality steps are tried from gentlest down; the first one that fits your target wins.
  3. See before you download — exact sizes plus a page preview of the result, so nothing is a surprise.

Tighter limit? Use the 100 KB target page. Prefer picking a quality instead of a size? The main Compress PDF tool does both — and splitting by size can cut a huge file into email-sized parts without quality loss.

Compressing to 1MB, honestly answered

Select your PDF above — the target is pre-set to 1 MB. The tool tries progressively stronger settings and keeps the best quality that fits. Switch the target to 2 MB, 10 MB, or any custom value in one click.
Usually, yes — 1 MB is roomy compared to a 100 KB portal cap, so most documents fit at good quality. The exact before/after size and the result preview are always shown, so you judge with your own eyes.
No. Everything runs in your browser — there's no upload wait, and the file never touches a server. For a 50 MB scan, skipping the upload alone saves minutes.
Almost always scans or photos embedded at print resolution. Re-rendering those pages at screen resolution is where the savings come from — text-only PDFs are usually small already, and we'll return them unchanged rather than bloat them.
Yes — free, no account, no file-size cap, no daily quota. Your device does the work, so we have no server bill to pass on.
