Questions about this browser tool

Can format conversion affect transparency?

PNG and WebP can preserve alpha transparency. JPEG cannot, so transparent areas are flattened against a background. Confirm the destination platform's requirement before choosing JPEG.

Does converting a file improve its quality?

No. Conversion changes the encoding container and may reduce size, but it cannot restore detail already missing from the source. Start from the highest-quality original available.

Are my images uploaded to a server?

No. Source files, QR values, GIF frames and PDF pages are processed in this browser with Canvas and local JavaScript libraries. The site does not upload the files or save outputs to account history.

What are the browser limits?

Use a current Chrome, Edge, Safari or Firefox release. Very large images, long GIFs and complex PDFs can be limited by available device memory, and encrypted PDFs may need to be unlocked first.
