Frequently asked questions
Yes, completely free — no hidden fees, no premium tiers, and no usage limits. You can convert as many images as you want, as many times as you want, without ever paying anything or creating an account.
No. All conversion happens directly in your browser using the JavaScript Canvas API. Your images never leave your device — they are not sent to any server, not stored anywhere, and not accessible by anyone else. This makes the tool both fast and 100% private.
The converter supports JPG, PNG, and WEBP formats. You can convert in any direction: JPG to PNG, PNG to JPG, JPG to WEBP, PNG to WEBP, WEBP to JPG, and WEBP to PNG. Support for additional formats may be added in future updates.
It depends on the format and quality setting you choose. PNG is a lossless format, so converting to PNG preserves full quality. JPG and WEBP are lossy formats — you can control the quality level using the quality slider (default is 92%, which provides an excellent balance between file size and visual quality).
WEBP is a modern image format developed by Google that provides significantly better compression than JPG and PNG. Converting your images to WEBP can reduce file sizes by 25–35% compared to JPG at the same visual quality. This is particularly useful for web developers and content creators looking to speed up their websites and reduce bandwidth usage.
The tool supports image files up to 20MB. Since all processing happens in your browser, the limit is designed to keep performance smooth on all devices. For most everyday images — photos, screenshots, graphics — 20MB is more than enough.
No installation required. The file converter works entirely in your web browser — no software to download, no plugins, no extensions. Just open the page, drop your image, and convert. It works on Windows, Mac, Linux, iOS, and Android.
Currently the tool converts one image at a time. After downloading your converted file, you can click "Convert another file" to immediately start the next conversion. Batch conversion support is being considered for a future update.
