Frequently Asked Questions

Are my files uploaded?

Tools process files in your browser, so files are not sent to our server. Ads or analytics, when enabled, may make their own requests.

Do I need an account?

No.

Is there a file size limit?

Each tool lists a maximum. Very large files may fail on devices with limited memory.

Why did my PDF barely shrink?

If a PDF is mostly text or already-optimized images, there is little to remove without changing its content.

Why did my PNG lose transparency in JPG?

JPG has no transparency. The converter fills transparent areas with a background color you can choose.

Which browsers work?

Current Chrome, Firefox, Edge and Safari.
