Compress PDF to 1 MB
A 1 MB limit is the everyday ceiling: resume and portfolio uploads, email attachments, WhatsApp and Slack shares. This page opens the compressor pre-set to 1 MB, which for most documents means modest compression and no visible change.
Get under a size limit
Picking a size limit automatically turns pages into compact images and dials quality down until the file fits. Nothing is ever uploaded — compression happens entirely in this tab.
Getting under 1 MB without regretting it
Resumes: prefer Lossless first
Recruiting systems parse text out of your resume. On the main tool, try Lossless before the 1 MB target — if that gets you under the limit, your text stays machine-readable.
Image portfolios
Photo portfolios compress well: a 12 MB lookbook comes down to under 1 MB with pages still presentable.
Email and chat
Many mail servers accept up to 25 MB, but staying under 1 MB means near-instant delivery and no bounce on strict corporate gateways.
Good to know
Will recruiters still be able to read my resume?
Yes. If the target forces image mode, text stays readable but stops being copy-pasteable — try Lossless on the main page first if an ATS will parse it.
What’s the difference between 1 MB and 500 KB?
About one level of quality. Use 500 KB only when the portal explicitly demands it; otherwise 1 MB keeps images sharper.
Can I compress a PDF on my phone?
Yes — the tool runs in the mobile browser, files are never uploaded, and the result downloads straight to your device.
