A 1 MB cap is generous for a short document and tight for a long one. It turns up on many application, admission and HR portals, and it is a sensible size for a document you want to email or message without it filling someone's inbox. This page opens with "Under 1 MB" selected, re-renders the pages in your browser and keeps the highest-quality version that fits, so a short scan barely changes and a long one gets as much quality as 1 MB allows.

What fits under 1 MB

Results from our 300 DPI A4 test scans and photo PDF:

1 page (1.9 MB): 547 KB at 200 DPI, close to the original to look at.
2 pages (3.9 MB): 570 KB at 150 DPI.
3 photo pages (1.9 MB): 730 KB at 200 DPI.
10 pages (19 MB): 493 KB at 72 DPI.
About 20 to 40 pages: fits only at 60 to 72 DPI. Beyond that, expect a miss.

When this is and isn't the right choice

Right choice: a scan or photo-heavy PDF that is a few MB and needs to drop under 1 MB with as little visible change as possible.
Wrong choice: a PDF you will print at high quality. 150 to 200 DPI looks fine on screen but is below print resolution, so keep the original for printing.
Wrong choice: a long report that has to stay searchable. Split it with Split PDF and send it in parts instead of turning every page into an image.

Tips for 1 MB targets

Try "Compression level" set to Medium first if you are not sure of your page count. If the result is under 1 MB you are done; if not, switch back to "Target file size".
Long files take a while, because each attempt renders every page. Browsers slow down background tabs, so keep this tab in front until it finishes.
For a file that misses by a little, removing one or two photo-heavy pages usually makes the difference. In Split PDF, "Page ranges" with "Combine into a single file" keeps only the pages you list.

How to use it

Drag your PDF onto the upload box, or click to choose it.
Leave "Under 1 MB" selected and click "Compress PDF".
Download the compressed copy once it shows the new size.

Frequently asked questions

Will compressing to 1 MB make my PDF blurry?

Not for a short document. A one or two page scan fits at 150 to 200 DPI, which looks the same as the original at normal zoom. In our tests a 1.9 MB single-page scan came out at 547 KB, and a 1.9 MB PDF of three photo pages at 730 KB, both at 200 DPI.

How long a document can I get under 1 MB?

Our 10-page, 19 MB scan came out at 493 KB at 72 DPI; the 96 DPI step was 1.03 MB, just over. By the same per-page sizes, about 20 pages fit at 72 DPI and about 40 at the lowest setting, 60 DPI. Past that, split the document.

My PDF is 1.2 MB and mostly text. Will this get it under 1 MB?

Possibly, but look at why it is big first. A text PDF of that size usually carries embedded fonts or a few large images. Rasterizing works, but it removes the selectable text; if the text matters, see whether whoever made the file can export it again at a smaller size.

Does 1 MB here mean 1,000,000 or 1,048,576 bytes?

The tool aims under 1,000,000 bytes, so the file passes a 1 MB limit counted either way. It displays sizes in 1,024-byte units, so a passing file can show as about 0.95 MB.

Is there a page or file size limit?

No fixed limit. Every page is rendered in your browser, so a very long or very large PDF is bounded by your device's memory and takes longer, since it may try several settings before one fits.
