How to Compress PDF to an Exact Size

Three steps, and the whole job usually takes less than a minute.

1

Upload Your PDF

Click Select PDF Document or drag the file into the box. The file stays on your device the whole time, nothing is uploaded anywhere.

2

Pick Your Target Size

Choose 100KB, 200KB or 500KB, or type any size you need, from 10KB up. The tool tries the best quality first and only lowers it as far as needed to fit.

Download Results

Press Compress PDF & Download and the file that fits your target saves straight to your device, ready to upload or send.

Why Use Our Compress to Size Tool?

A quality slider makes you guess. A target size does not.

Exact Size, No Guessing

You set the number your form or portal asks for, and the tool works until the file fits it. No more compress, check, compress again.

Instant Processing

The compression happens in your browser the moment you press the button. No queue, no waiting for an upload to finish.

Guaranteed Privacy

Because the file never leaves your device, private documents stay private. There is nothing on a server to delete later.

Cross-Device Ready

Works on phones, tablets and computers alike, which is handy when the form is sitting in your phone gallery.

Best Quality That Fits

The tool tries the highest quality first and only steps down as far as your target needs, so you never lose more quality than necessary.

Popular Ways to Compress PDF to a Size

Job Applications

Portals and company forms often cap uploads at 100KB or 200KB. Shrink your CV or certificates to fit on the first try.

Government Forms

Admission, exam and ID forms print exact KB limits. Hit the number instead of guessing.

Email Attachments

Get a photo-heavy PDF under the limit instead of splitting it into pieces.

Uploading to Apps

Chat apps and portals that reject large files accept the same document once it fits.

Frequently Asked Questions

Can it always reach my target size?

Not always, and that is worth knowing before you start. The tool shrinks the photos inside your PDF. If your file is mostly text with no photos, there is almost nothing to shrink, and if it has many pages, even the smallest photos add up. When the target cannot be reached, the tool shows you the smallest size it could make and explains why, instead of failing quietly.

What happens to my file if it is already under the target?

Nothing. The tool tells you it already fits and lets you download the original file unchanged.

Will my text still be selectable after compression?

Pages with photos are re-saved as images, so the text on those pages is no longer selectable. Pages that are text only stay as text and keep working exactly as before. The layout and appearance of every page stay the same.

How small can it go?

You can type any target from 10KB up. Very small targets on long or photo-heavy files may not be reachable, and the tool will tell you the smallest size it could make.

Is it really free, with no watermark?

Yes. No signup, no watermark, no page limit added by us. The file is processed locally in your browser.
