Frequently asked questions
Is WebP supported everywhere?
Yes, in every modern browser (Chrome, Firefox, Safari, Edge — all major browsers since 2020). Email clients and older software may still prefer JPG; in that case stick with JPG.
How much smaller will the file be?
Typically 25-35% smaller than JPG at the same visual quality. For images with flat colors or gradients, savings can exceed 50%.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
