Frequently Asked Questions

Are my images or PDFs uploaded to a server?

No. Image conversion, image compression, watermarking, and PDF merge/split all run in your browser. Files are never sent to a server, so you can safely work with contracts or personal photos.

What image format is best for websites?

In most cases WebP is smaller than JPG or PNG with almost no visible quality loss, which helps page speed. Convert with the WebP Converter, then shrink the file further with the Image Compressor.

Can I use the QR codes and barcodes commercially?

Yes. You can freely use generated QR codes and barcodes on business cards, posters, product labels, and more. Before printing, always check that they scan with a real phone or scanner.
