Save JPG pictures as WEBP
Drop your JPEG pictures on the page or pick them from a folder. A full photo shoot works just as well as a single image.
Try the Smaller, Balanced or High preset, read the measured file size, and set a longest side if the originals are huge.
Hit Convert to WebP and grab the files one at a time, or together in a single ZIP archive.
Made for the jobs people really do with WebP
Numbers from your own picture
The size readout comes from actually encoding the selected image at your current settings, not from a rule of thumb. With several files, it projects a total for the whole set too.
Spot artefacts before they go live
Slide the split line across the preview to see the JPEG on one side and the WebP on the other, or tap 100% to inspect the middle of the frame pixel by pixel.
Web-ready sizes in one click
Cap the longest side at 3840, 2560, 1920, 1600, 1280, 1024 or 800 px, or type your own width and height. Proportions stay intact and small pictures are never blown up.
Metadata on your terms
Camera details are stripped unless you ask to keep them. If you do, location coordinates can still be wiped separately, and sideways phone shots are straightened automatically.
When to convert JPEG to WebP
WebP pays off wherever pictures are shown in a browser and every kilobyte counts. A few typical cases:
- Bloggers and online shop owners who want product shots and article photos to appear quickly on a slow mobile connection.
- Real estate agents preparing a gallery of property pictures for a listing page that accepts WebP uploads.
- Freelance web designers handing a client a folder of web-ready images, each capped at 1920 px.
- Teachers adding illustrations to a course page or class website without making students wait for heavy files.
- Office teams trimming photos for an intranet or newsletter archive that keeps growing.
A routine that works for most batches
Start with Balanced, then drag the split line over an area with fine texture such as hair, foliage or fabric. If you see no difference, try a lower value and check again; if edges look soft, move up toward High. For a blog or shop, a longest side of 1600 or 1920 px is plenty, and resizing often saves more than the quality setting alone. Leave camera metadata off unless a photographer needs credits and lens details preserved.
Good to know
The format tops out at 16383 pixels per side, so very wide panoramas are scaled down to fit. Phone photos captured in a wide colour space are written in standard sRGB. When you ask for lossless output, the finished file is inspected and the toolbox reports whether your browser delivered true lossless or its best lossy version. Going the other way later? The WebP to JPG tool restores a format that older software can open.

Questions people ask about this task
Is it worth switching my website images from JPEG to WebP?
Usually, yes. At comparable quality a WebP tends to be a good deal lighter, which speeds up page loads. The tool shows the exact saving for your picture, so if a JPEG is already squeezed hard and barely shrinks, you find out before converting.
Can I turn a whole folder of JPEGs into WebP at once?
Yes. Select every file in one go, preview any of them from the drop-down list and check the estimated total. The results download together as a ZIP, and any file that cannot be read is skipped and named at the end.
Will my pictures look blurry after the switch to WebP?
At the Balanced (80) or High (90) presets most photos look unchanged at normal viewing size. Open the 100% view to judge fine texture, and keep lower values such as 60 for small thumbnails.
Why is my WebP file bigger than the original JPEG?
That happens with the lossless option or a very high quality setting on a JPEG that was already compressed. Lossless keeps every decoded pixel but cannot recover detail the JPEG threw away, so pick a lower quality or reduce the dimensions instead.
Does this work in Safari on an iPhone or a Mac?
Safari shows WebP images but has no encoder to create them, and all iPhone and iPad browsers run on its engine. Switch to Chrome, Edge or Firefox on a computer or an Android phone.
Are my JPEG files sent to a server?
No. Every picture is processed inside your browser tab and never leaves the device. There is also no sign-up and no watermark on the output.
