Compress a PDF to a target size

Hit a 1 MB, 2 MB or 500 KB limit without uploading your file anywhere.

Files never leave your device · No upload · Free

Upload forms, job portals and government sites often cap a PDF at a specific size, 1 MB, 2 MB, sometimes 500 KB, and reject anything larger. Instead of guessing with quality sliders, use the target-size mode: enter the size you need and the compressor works to fit under it, entirely in your browser. Your file is never uploaded, and you see the final size before you download.

How to compress a pdf to a specific size (kb or mb)

  1. 1

    Add your PDF

    Drop in the file you need to shrink.

  2. 2

    Choose “Target size”

    Switch to target-size mode and type your limit, for example 1 MB.

  3. 3

    Compress and download

    Get a file at or under your target, built on your device.

Why compress to a size, privately?

The PDFs you need to fit a form are often personal: IDs, applications, financial documents. Hitting the size limit locally means you solve the problem without first handing the file to a compression service.

Frequently asked questions

Can it hit an exact size like 1 MB?+

It gets as close as it can while staying at or under your target. Some PDFs cannot go below a certain size without becoming unreadable, and it tells you when that happens.

Will the quality drop?+

To reach a small target it may rasterise pages, which trades some sharpness for size. For modest targets, text usually stays selectable.

Is my file uploaded to compress it?+

No. The compression runs in your browser, so the file never leaves your device.

Is it free?+

Yes, with no sign-up.
