How to compress a PDF to 2MB
Three steps, all in your browser.
Add your PDF
Drag and drop a PDF, or click to browse. It stays on your device.
Check the 2MB target
The size is already set to 2MB. Change it if you need a different limit.
Compress and download
Download a PDF at 2MB or under, with as much quality kept as possible.
When you need 2MB
2MB is a common limit for CMS uploads, forms, and email gateways. Most phone-scanned documents are several times bigger, and a light pass that keeps images near full quality is often enough.
What to expect at 2MB
As a rough guide, 2MB holds a long scanned document or a report with many images at good quality.
Tips for getting a PDF to 2MB
- A light pass is usually enough at 2MB: most limits this size exist to stop huge camera scans.
- If your PDF is already under 2MB, it is returned unchanged.
- Keep the original of anything important: compressing is one-way, so save the smaller copy under a different name.
Nothing uploaded
PDFs are compressed in your browser, so private documents never leave your device.
Highest quality that fits
It searches for the best quality that keeps the file at 2MB or under, instead of guessing a setting.
Text stays sharp
Only the images inside are recompressed, so text stays selectable unless you allow flattening.

Frequently asked questions
Drop your PDF into the box above and click Compress. The size is already set to 2MB: MonsterConvert works out how far the images inside can be recompressed to get the file at or under that size, and keeps as much quality as it can. Then download the result.
Most of a PDF's size is usually the pictures inside it: scanned pages and photos. Images stored as JPEG are recompressed at a lower quality and, if they are larger than they need to be, at a smaller pixel size. Text, fonts, and links are not touched, so text stays sharp and searchable.
A PDF made from a document (Word, LaTeX, a web page) is mostly text and fonts, not images, so there is little to recompress. Images stored in other ways, such as PNG-style images, images with transparency, or CMYK images, are also left as they are, and the result tells you how many images were skipped. To shrink a text-only PDF much further, use the Maximum level, which flattens every page into a picture.
Flattening turns each page into a picture of itself. That can reach very small sizes, but the text can no longer be selected, searched, or copied, and links stop working. It is off unless you choose Maximum or allow it when a size target can't be met any other way.
Only if it is bigger. Scans from a phone app are often 3 to 10MB, so yes for those; documents exported from software are usually already small.
Very close in most cases. The images are recompressed only as much as needed, and text and vector graphics are not touched.
Some PDFs can't get to 2MB without flattening (for example, long text documents). When that happens the result says it got as close as it could, instead of claiming success, and you can choose to allow flattening and try again.
The result is at or under your target, as close to it as the search gets, so quality is not thrown away for nothing. MonsterConvert counts 1 KB as 1,000 bytes, so the file also passes a site that counts 1,024. If the PDF is already smaller than the target, it is returned unchanged.
Rewriting a PDF invalidates a digital signature and can break PDF/A conformance, so you'll see a warning when either is detected. Password-protected PDFs can't be compressed: unlock them in your PDF viewer first (open it and Print -> Save as PDF), then add that copy.
No. The PDF is compressed inside your browser using WebAssembly, so it never leaves your device. That makes it safe for contracts, IDs, and other private documents.
Because everything runs on your device, very large PDFs need a lot of memory. Files over 50 MB show a warning, and files over 250 MB are refused. If yours is that big, split it first and compress the parts.
