Compress PDF to 1 MB

The most common upload limit on the web — hit it in one step, with quality kept as high as possible.

Compression re-renders image-heavy pages as JPEG images. With “Keep text selectable” on, pages made of text and vector graphics are only re-saved and stay searchable; pages that are mostly pictures are flattened.

Court e-filing systems, HR and government portals and many contact forms stop at 1 MB, and smaller attachments simply travel better by email. At 1 MB a scanned document of ten or more pages can still look crisp, so the tool usually needs only its lightest settings.

Pick a different target from the list if the form you are filling in asks for another limit. Nothing is uploaded — the PDF is compressed by your own browser.

Frequently asked questions

Is 1 MB 1000 KB or 1024 KB?

The tool uses 1 MB = 1024 KB, and portals that count 1 MB as 1000 KB may need the 500 KB target to be safe.

Will it look worse?

Usually not noticeably: getting under 1 MB rarely needs more than screen-quality images (about 150 dpi).

My PDF is 50 MB. Can it reach 1 MB?

A long, photo-heavy file may not. Split it with Split PDF by Size, or remove pages you do not need, then compress each part.

Is my PDF uploaded to compress it?

No. Pages are re-encoded inside your browser; the file never leaves your device.
