Compress PDF to 1MB

The 1MB ceiling shows up where whole files travel: resume-plus-certificates uploads on job portals, annexures in court e-filing systems, tender documents on procurement portals, and corporate email gateways that bounce anything larger. A megabyte holds twenty-plus readable scanned pages, so this is rarely about brutal compression — it is about taking a 6MB phone scan down to something a system will accept without visibly touching the quality. The search runs entirely in your browser.

The output is guaranteed at or under this size whenever the page count allows it — the practical floor is roughly 10 KB per page.

70% keeps scans clearly readable; drop lower only when size matters more than crispness.

Honest trade-off: this compressor re-renders every page as a JPEG image. Scanned documents shrink dramatically, but the result has no selectable text — like a photocopy. If you need the text layer kept, don't use a rasterising compressor.

Landed under your {{ targetLabel }} target.

Even at the lowest quality and scale, this document cannot reach {{ targetLabel }} — the practical floor is about 10 KB per page. This is the closest result; splitting the PDF into parts is the reliable fix.

Pages are now images — text is no longer selectable.

How to use this tool

  1. Add the PDF

    Drop in the oversized file — commonly a phone-scanned bundle of 10–30 pages that ballooned past several megabytes.

  2. Keep the 1MB target

    The preset is 1024KB. Some systems cap at exactly 1000KB rather than 1024 — if yours does, type 1000 to be safe.

  3. Compress and download

    Passes run until one fits under the target; the achieved size is displayed so you know it will clear the gate before you upload.

Questions people ask

Where is a 1MB PDF limit actually enforced?

Job application portals (resume and certificate bundles), several High Court and district court e-filing systems for annexures, government tender portals, and plenty of corporate email setups that reject large attachments at the gateway. It is the standard "whole document" cap, where 100–200KB caps are per-certificate.

Is 1MB actually 1024KB or 1000KB?

Depends on the system — most treat it as 1024KB, but some validate against a round 1,000,000 bytes. The preset here is 1024KB; if a portal rejects a 1010KB file, set the target to 1000 and rerun. The tool reports the exact byte size either way.

How many pages survive readably under 1MB?

Twenty to thirty scanned pages at solid quality, more if you accept softer output. Documents under ten pages usually land far below the cap at nearly full sharpness, because the search keeps the highest quality that fits.

Why is my scanned PDF so huge in the first place?

Phone scanning apps save each page as a photo at camera resolution — 12 megapixels for what is ultimately A4 text. Re-rendering at document resolution is why a 6MB scan drops under 1MB with no visible difference on screen or paper.

Is it safe for court documents and job applications?

Yes — everything runs on your device, with no upload endpoint on this site. Petitions, affidavits and offer letters stay in your browser's memory from drop to download.

What if even 1MB is not enough?

The tool returns the closest smaller size and says the target was missed rather than pretending. At that point split the bundle — most e-filing systems accept multiple annexure files, and two 900KB parts beat one illegible 1MB file.
