About the formats
JPG
JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.
Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.
WebP
WebP is a modern image format developed by Google that supports both lossy and lossless compression, along with transparency and animation. At comparable visual quality it usually produces noticeably smaller files than JPG or PNG.
Every current browser supports WebP, which makes it an excellent default for web delivery. Outside the browser the picture is mixed: older desktop software, some email clients, and legacy systems may fail to open it. If a recipient cannot view a WebP file, convert it to JPG for photos or to PNG when transparency must be preserved.
Privacy and file handling
Processing happens in your browser, so the selected file is not uploaded.
- Browser-local processing
- The conversion runs on this device after the page loads.
- No file upload
- The source image does not need to leave your browser.
- No model API
- This basic tool does not send the file to an AI model.
JPG to WebP troubleshooting
- The WebP looks slightly smoother than my JPG
- Re-encoding a lossy image is never pixel-identical: WebP tends to smooth fine grain and noise. Raise the quality setting if detail matters; if you need an exact copy of the pixels, keep the original JPG.
- A website or app rejects my WebP file
- WebP is universal in browsers, but some upload forms, older CMSs, and print services only accept JPG or PNG. Keep the original JPG for those destinations and use WebP where it is supported — your own website, for example.
- Is this conversion private and free?
- Yes on both counts: the conversion runs entirely in your browser, so the photo is never uploaded to any server, and single-file conversions are free with no usage limit.
FAQ
- Why convert JPG to WebP?
- WebP offers better compression than JPG at the same visual quality, so your photos load faster on websites and use less storage.
- Does conversion happen in the browser?
- Yes. Your JPG files are converted entirely within your browser. Nothing is uploaded, so your images stay private.
- Is there a file size limit?
- Free accounts can upload files up to 50 MB. Paid users can upload up to 200 MB.
- What quality should I use?
- A setting of 75–85 usually matches the visual quality of the source JPG at a much smaller size. Avoid converting back and forth repeatedly — each lossy re-encode discards a little more detail.
