Frequently Asked Questions
Is this PDF compressor free?
Yes, it’s completely free with no sign-up, and you can use it as many times as you like.
Are my files uploaded anywhere?
No. Compression happens entirely in your browser, so your PDF never leaves your device.
How do I compress a PDF to under 2 MB for a job portal?
Use the Balanced or Screen preset and watch the live size readout. If you need to go smaller, lower the image quality slider until it’s under the limit.
Will compressing reduce the quality?
Some image quality is traded for size. Balanced keeps it good for screens and uploads; choose Print if you need higher quality for printing.
What’s the maximum file size I can compress?
Up to 50 MB.
