About compressing to this size

1 MB is the usual limit for resumes, portfolios and supporting documents on job portals, and a safe size for email. Scanned documents of 10–20 pages usually fit at good quality.

How it reaches 1 MB: each page is redrawn as a JPEG image, and the tool searches resolution and quality settings for the best-looking version that is still under 1 MB. This works best for scanned PDFs and photos of documents. Typed PDFs (from Word or a website) are usually small already — if yours is already under 1 MB, the tool tells you and keeps it unchanged.

Good to know: because pages become images, text in the compressed file can’t be selected or searched. That is fine for uploads, but keep your original for editing.

Tip: For a typed resume exported from Word, the PDF is usually already small — check its size before compressing.

Frequently asked questions

How do I compress a PDF to 1 MB?

Choose your PDF above — the target is already 1 MB — and click “Compress PDF”. Download the result once it says it is under 1 MB.

What if it can’t get under 1 MB?

You’ll get the smallest version possible and a note. Tick “black & white”, or remove extra pages with Delete PDF Pages, then try again.

Is my PDF uploaded anywhere?

No. Compression happens in your browser, so private documents never leave your device.

Can I still read the text after compressing?

Yes, it stays readable, but it becomes part of an image, so you can’t select or copy it.
