Convert JPG to WebP
Convert JPG photos to WebP for noticeably smaller files at the same visual quality — perfect for the web. Runs locally in your browser.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
How much smaller does WebP get?
For photographic content, WebP typically lands 25–35% smaller than a JPG of equal visual quality — its encoder simply predicts image content better than the 1992-era JPEG design can. On an image-heavy page that difference compounds into meaningfully faster loads and lower bandwidth bills.
Where JPG still wins
Keep JPG when the file is headed somewhere WebP is awkward: email attachments viewed in old clients, print services, government portals, or software that predates 2020. For anything displayed in a browser, WebP support has been universal for years and there is no longer a reason to hold back.
Re-encoded on your device
Each JPG is decoded and re-encoded to WebP locally — your photos never travel to a server. Converting a whole image library is just a matter of dropping it in and downloading the ZIP.
Frequently asked questions
- Which formats are supported?
- You can convert to and from JPG, PNG, WebP, AVIF and BMP, and convert from HEIC/HEIF (iPhone photos). Browsers cannot create HEIC files, so HEIC is input-only. Output formats your browser cannot encode are detected and disabled automatically.
- Can I convert HEIC to JPG?
- Yes. Drop in a HEIC photo from an iPhone and choose JPG (or PNG/WebP). The HEIC file is decoded locally in your browser with a bundled decoder — it is never uploaded anywhere.
- Is transparency preserved?
- Yes, when converting to a format that supports an alpha channel (PNG, WebP, AVIF). For formats without transparency (JPG, BMP), you can pick a background color for transparent areas.
- Is my image uploaded?
- No. Conversion runs entirely in your browser — your images never touch a server.
- What is AVIF and should I use it?
- AVIF produces the smallest high-quality files. Encoding support varies by browser, so PixelVault enables it only when your browser can create AVIF files.
- Can I convert many images at once?
- Yes. Batch-convert a whole folder of images and export them together as a ZIP.
