Compress PDF to 1 MB

Reduce a PDF to under 1 MB for online forms.

Upload a PDF to make it smaller than 1 MB.

Strong compression is tried first so your text stays selectable. If that is not enough, pages are turned into lighter images to fit the limit.

Compress PDF to 1 MB online, free and private

Upload forms often refuse PDFs above 1 MB, especially for visa, bank and administrative uploads. This tool makes your PDF fit: it first applies strong compression, which keeps your text selectable. If that is not enough, it turns the pages into lighter images at the best quality that still fits under 1 MB.

Frequently asked questions

How do I compress a PDF to 1 MB?

Choose your PDF, keep 1 MB as the maximum size and click Compress PDF. The new size is shown before you download.

Will the text stay selectable?

Yes when strong compression is enough. When the limit is very small, pages are saved as images to fit: the PDF still looks the same, but its text can no longer be selected.

Can I choose another size?

Yes. Type any size in the Maximum size in KB field, for example 300 KB or 2000 KB.

Is my PDF uploaded?

No. Compression happens in your browser, so your document never leaves your device.
