FAQ
No. Conversion happens inside your browser using the Canvas API. Nothing is transmitted, stored or logged. You can disconnect from the internet after the page loads and it will still work.
No. Most converters cap you at 1 GB or 20 files because they pay for server processing. There is no server here, so there is no cap. Very large images may simply take a moment on slower devices.
WebP is the best default for the web — typically 25–35% smaller than JPG at matching quality, with support in every modern browser. AVIF is smaller still. JPG is the most universally compatible. PNG is for transparency and flat graphics.
JPG cannot store transparent pixels, so anything transparent has to be filled with a solid colour. This tool fills with white, which is what most people expect. If you need to keep transparency, convert to PNG, WebP or AVIF instead.
Browsers can read many formats but can only write a limited set. EPS, PSD, SVG and TGA would need server-side processing, which would mean uploading your files. We chose privacy instead.
Yes, identical. The two names exist only because older systems limited file extensions to three characters.
Yes, you can use the compressor tool separately or within the converter by selecting the same input format and lowering the quality slider.
Yes, open the gear icon on any file in the converter and set a maximum width; the height follows automatically. You can also use the dedicated resizer tool with presets.
No, ToolBench is completely free and requires no sign-up. All tools are accessible without registration.
