PDF tools · preset 500 KB
The limit said: PDF, under 500 KB. This page is set to that target before you start. Pick the file, run the job, and take away a PDF that fits the door, with the exact final size printed on the result. Everything runs in your browser; the file is never uploaded. A different target lives on the Compress PDF page.
For email attachments, job boards and university portals with a 500 KB limit, the working limit of daily office life.

Fixed by this page, the email-and-boards preset. The page probes the photos inside your PDF, picks a starting setting from the probe, and steps down only as far as it must, so the photos keep as much quality as the door allows.
Before you run it: a scanned page is a picture, so squeezed scans come out softer to read. And a PDF whose pictures are not JPEGs may barely shrink at all. Both are properties of the file, not a fault in the run.

Most of a photo-heavy PDF is the photos inside it. This page reads those photos, recompresses them at a smaller size and quality chosen from a quick probe of your file, rebuilds the PDF, and checks the result against 500 KB. In our tests, an 11.65 MB photo PDF landed at 415 KB, under the line with room to spare.
We shrink PDFs by recompressing the images inside them and tidying the file. A PDF that is already tightly compressed may not get much smaller. We always show you the before and after size, and if we could not make it smaller, we say so and give you back your original. Photos stored in formats other than JPEG are left as they are in this version, and the result line tells you when that happened.
A password-protected PDF cannot be opened by this tool. Take its password off first with the unlock tool, then bring the file back.
Because 500 KB is the working limit of daily office life: the attachment an inbox accepts without complaint, the document a job board or university portal takes. This page is the Compress PDF tool with the target already set to 500 KB, so the job is two clicks: pick the file, run.
No, and the page will not pretend. In our tests, an 11.65 MB photo PDF landed at 415 KB. A PDF whose bulk is not photos, or one that starts only slightly over, may not have enough to give up; when the target cannot be reached, the result line states the smallest size it could reach before you download.
The photos inside are recompressed smaller and softer. Text and drawings stay exactly as they were. The result line prints the size and quality setting used, so you can judge the trade.
