Quikbench
JPG, PNG, and WEBP conversion happens right here in your browser tab. Nothing is uploaded to a server — open your network tab if you don't believe it.
Drop in one or more images. Pick the format you want out, then convert — every file is converted at the best possible quality automatically. Supports JPG ⇄ PNG, JPG ⇄ WEBP, and PNG ⇄ WEBP — convert in either direction between any of the three.
Every tool on Quikbench follows the same rule: your files are read, converted, and turned into a download entirely inside this browser tab — nothing is ever uploaded to a server.
Converts between JPG, PNG, and WEBP using your browser's built-in Canvas. Drop in a single image to pick its target format individually, or queue several and convert them all to the same format in one batch.
With a single file queued, a dropdown next to it lets you choose its output format and convert it on its own. Queue two or more and a batch control appears, letting you send every file to the same format — or still override individual files using their own dropdown.
Because it relies on your browser's native image decoding, the converter accepts essentially any image type your browser can open, and outputs to JPG, PNG, or WEBP. Multiple converted files can be downloaded together as a single .zip.
JPG suits photos and complex images where small file size matters more than perfect edges — it uses lossy compression, so repeated conversion back and forth will gradually degrade quality. PNG is lossless and supports transparency, making it the right choice for logos, screenshots, and graphics with sharp edges or text, at the cost of larger file sizes for photos. WEBP generally gives the smallest file size at comparable quality to JPG or PNG, and is well supported by modern browsers, but is less universally accepted by older software.
Converting JPG to PNG and back doesn't recover any detail lost in the original JPG compression — PNG can only losslessly preserve whatever is fed into it. If you need the highest quality, always convert from the original source file rather than from a file that's already been through a lossy conversion.
PNG is lossless, so converting JPG to PNG preserves exactly what's in the JPG (including any compression artifacts already present, but no further quality loss is introduced during conversion).
Yes — drop in multiple images and this tool converts and lets you download them together, all processed locally without uploading to a server. Each batch is capped at 20 files and 300MB combined, shown live as you add files, to keep the tab responsive on lower-end devices.
WEBP is generally 25–35% smaller than JPG at similar visual quality, making it a good choice for web use where file size matters.
Converting to PNG or WEBP (lossless mode) preserves quality; converting to JPG applies lossy compression, so some detail is lost, though usually not visibly at normal quality settings.
Yes — queue several images and each is converted individually to your chosen output format, ready to download.
No — JPG doesn't support transparency, so transparent areas will be filled with a solid background color (typically white) during conversion.
