The PDF compressor that hits any size

Drop your PDF into the compressor at the top of this page. By default it shrinks the file to half its original size. Drag the slider for a different percentage, or switch to Exact size and type a limit like 200KB or 2MB. Click Download when it finishes. No account and no watermark.

Yes, completely. There is no file size limit, no limit on how many PDFs you compress, no daily cap, no signup, no watermark and no paid plan. Everything runs on your own device, so it costs nothing to run.

No. The compression runs entirely inside your browser. Your file is never uploaded, stored or seen by anyone, which makes this tool safe for contracts, IDs, bank statements, tax forms and medical records.

Switch the target to Exact size, tap 100KB, 200KB, 300KB or 500KB (or type any number), then drop your file. The compressor searches for the highest quality version that still fits under your limit. Long scanned documents may need Black & white or Maximum mode to reach 100KB.

Choose Exact size, pick 2MB, 5MB or 10MB, and drop the PDF. This is the fastest way to meet upload limits on job portals, visa and university applications, email attachments and Discord, which allows 10MB on free accounts.

The default target is 50% of your original file size. A 4MB PDF becomes about 2MB. Drag the slider anywhere from 5% to 95% to trade quality for size. Lower percentages make smaller files with more visible image compression.

In Smart mode, text, vector graphics, links and bookmarks are kept exactly as they are. Only photos and scanned images are re-encoded, and the tool always picks the best image quality that meets your target. Quality loss only becomes visible at very aggressive targets.

Some PDFs are mostly text and fonts, which are already compact. When a target cannot be met, you still get the smallest version we could make and a clear notice. To go smaller, turn on Black & white, switch to Maximum, or split the file and keep only the pages you need.

Smart keeps text sharp and selectable and compresses the images inside the PDF. If that is not enough to hit your target, it can flatten pages unless you tick Never flatten. Maximum turns every page into an optimized image, which gives the smallest files and also flattens forms and annotations.

Open this page in Safari or Chrome, drop the PDF, and download the result. Preview's built-in Reduce File Size filter also works, but it offers no size control and often makes scans blurry. Here you choose the exact percentage or size you need.

Open this site in Safari or Chrome on your phone, tap Choose PDF files, pick the document from Files or Downloads, and tap Download when it is done. On iPhone the compressed file is saved to Files, in the Downloads folder.

Yes. Turn on Black & white before compressing. Images become grayscale, which usually makes the file smaller too. Choose Maximum as well if you want colored text and graphics converted, like a black and white scan.

Choose Maximum mode and compress. Every page is rendered to an image, so form fields, comments, stamps, signatures and layers are merged into the page and can no longer be edited. The result also looks like a scanned PDF.

Yes. Drop as many PDFs as you like. They are compressed one after another with the same settings, and you can download each file separately or all together as a ZIP.

The best PDF compressor lets you hit an exact size without ruining quality, and does not upload private documents. This tool does both for free with no limits. Desktop tools like Adobe Acrobat work well but are paid, and Ghostscript is free but command line only.
