JPG to WebP
Convert JPG images to WebP, the format every current browser supports and every page loads faster with. Furtu re-encodes each file in your browser at a quality you control, and shows the before and after size so you can see the saving rather than take it on trust.
WebP at 80% is usually indistinguishable from the original JPG and roughly 30% smaller. Below 50% artefacts become obvious in skies and gradients.
How jpg to webp works
- Add your JPG filesDrop in one image or a whole batch of up to 20. Each is checked against the real JPG file signature.
- Set the qualityLeave it at 80% for photographs. Raise it towards 90% for images with fine text, or drop it towards 60% to prioritise file size.
- Download the WebP filesEach image is re-encoded locally, named with the .webp extension and shown with its size before and after.
What you get
Turn JPG photos into WebP and cut the file size by around a third. Everything happens inside this page: the file is read by your browser, transformed in memory and handed straight back to you as a download. There is no upload queue, no waiting for a server, and nothing left behind when you close the tab.
Supported formats
Furtu accepts .jpg, .jpeg, .png, .webp, .avif, .gif, .bmp, .svg, .ico, .heic, .heif files up to 100 MB each, and processes up to 20 files in one run.
- Every file is checked against its real file signature, not just its name, so a renamed or corrupt file is rejected with an explanation instead of failing halfway through.
- Files over the limit are refused up front rather than after a long wait.
Limitations, stated up front
- Converting from JPG is a lossy step, so the file is decoded and written again. The result is close to the original but not identical to it.
- If the source is a PNG or WebP rather than a JPG, it still works — the tool converts whatever you give it — but the page is aimed at JPGs.
- Animated GIFs and SVGs are rejected. A canvas cannot preserve GIF animation and cannot re-encode vector art without rasterising it.
- Very old browsers without WebP support cannot display the result. Every current browser is fine.
Frequently asked questions
Will converting JPG to WebP make the image look worse?
At the default quality of 80%, almost never. WebP is a more efficient encoder than JPG, so at the same setting it usually produces a smaller file at the same perceived quality. Where you do notice a difference, it appears first in skies, gradients and dense fine detail.
Do my photos get uploaded?
No. Furtu decodes and re-encodes the file inside your browser. The JPG never leaves your device, so this is safe for personal photos, unreleased client work and anything with people in it.
How much smaller will the files be?
For photographs, expect 25–35% smaller at the default quality. Screenshots and images with large flat areas often do much better. A JPG that was already saved at maximum quality gives up more than one saved at a moderate setting.
Is WebP supported everywhere?
By every current version of Chrome, Edge, Firefox, Safari, Chrome for Android and Safari on iOS. It has been broadly supported since 2020. The gaps are old software: some email clients and a handful of content management systems still refuse it, which is when you want “WebP to JPG” instead.
Does the conversion keep my EXIF data?
No, and that is a benefit here. A canvas cannot copy camera information onto a new file, so the WebP comes out without GPS coordinates, camera model or timestamps. If you need those, keep the original JPG.
