When you need a PDF under 1 MB

A 1 MB PDF limit is typically used for larger multi-page documents, résumés and combined certificate sets. A 1 MB (about 1024 KB) limit is generous — it comfortably fits a multi-page scanned document, a résumé with graphics, or several certificates combined into one PDF. It is a common ceiling on portals that accept richer attachments.

Tip for getting under 1 MB

Merge all your pages into one PDF first (with our Merge or JPG-to-PDF tools), then compress the whole document to 1 MB in one pass so every page stays consistent.

Need a smaller target instead? Try 500 KB or 200 KB, or use the full PDF toolkit to merge and split first. Your file never leaves your device.

⚠️ Upload limits vary between portals — always confirm the exact maximum size in the official instructions.

Frequently asked questions

Is 1 MB enough for a multi-page PDF?

Yes. 1 MB easily holds several scanned pages at readable quality. If your document is much larger, this tool reduces it under 1 MB while keeping the text legible.

How do I compress a PDF to 1 MB?

Upload your PDF above — the target is preset to 1 MB (1024 KB). The tool rasterises the pages and lowers the quality just enough to bring the file at or under 1 MB, then lets you download it. Everything runs in your browser; nothing is uploaded.

Will the pages stay readable?

Yes — at a 1 MB target the tool keeps high quality, so the pages stay sharp. 1 MB is generous, so most documents compress with little visible change.

Is it free and private?

Completely free with no sign-up or watermark, and the PDF is processed entirely on your device — it is never uploaded to a server.
