Best for scanned or image-heavy PDFs. The target is preset to 500 KB.

When you need a PDF under 500 KB

A 500 KB PDF limit is typically used for full document sets, resumes and detailed multi-page scans. A 500 KB cap is one of the more generous PDF limits — it suits a full document set, a resume with graphics, or a detailed multi-page scan. Many portals that accept richer attachments use a 500 KB ceiling.

Tip for getting under 500 KB

At 500 KB you have headroom, so scan at a higher resolution for maximum legibility and simply confirm the final file lands under 500 KB — no need to over-compress.

Need a different limit or a general compressor? Use Compress PDF, and for the rest of your application try our full PDF toolkit — merge, split and convert. Your file never leaves your device.

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

Frequently asked questions

Do I even need to compress for a 500 KB limit?

Often a multi-page phone scan already exceeds 500 KB, so a light compression brings it under the cap while keeping excellent, fully readable quality.

How do I compress a PDF to 500 KB?

Upload your PDF above — the target is preset to 500 KB. The tool rasterises the pages and lowers the quality just enough to bring the file at or under 500 KB, then lets you download it. Everything runs in your browser; nothing is uploaded.

Will the text still be readable after compression?

Yes — the tool keeps the highest quality that fits under 500 KB, so the pages stay legible. Very small targets on a heavy scan will look softer; scanning in greyscale first helps a lot.

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.
