Compress PDF to 1 MB so it attaches to an email or passes an HR, onboarding or bank KYC upload. With 1 MB set as the target, most documents shrink with text left sharp and searchable.

How to get a PDF under 1 MB

  1. Click "Choose file" and select the large PDF.
  2. Keep Target size at 1 MB, which is already filled in.
  3. Click "Compress PDF" to start.
  4. Click "Download" and attach or upload the result.

Why 1 MB is usually easy to reach

A 1 MB limit leaves plenty of room. Most bloated PDFs are large because of high-resolution photos or phone scans. The tool first removes leftover data, then re-encodes those images at a lower size. In most cases it stops there, so text and vector graphics are untouched and the document still prints well.

The page-image fallback is mainly needed for very long scanned files, such as a 40-page statement scanned in colour. If yours is one of them, splitting it into parts with the Split PDF tool may be better than flattening every page.

Frequently asked questions

Why do HR and KYC portals limit files to 1 MB?

Onboarding systems and bank verification portals store documents for many customers and employees. A 1 MB cap keeps uploads quick on slow connections and storage costs predictable.

Will email accept the file after compressing?

A file under 1 MB is well within the attachment limits of common email services. It also downloads quickly for the person receiving it, even on mobile data.

Will my document still look good when printed?

Usually yes. At 1 MB the tool rarely needs to flatten pages, so text prints crisply. Photos inside the PDF may be slightly softer than the original.

Can I set a different limit, like 2 MB or 500 KB?

Yes. Type any size in KB into the Maximum file size box, for example 2048 for 2 MB, or tap the 500 KB button.

My phone photo PDF is 15 MB. Can it get under 1 MB?

Usually, yes. Phone photos are much larger than a document needs, so resizing them saves a lot. Large files take longer to process on older phones.

What if the result is still over 1 MB?

The tool says so and shows the smallest size it reached. Delete unneeded pages or split the document, then compress each part.
