Image Converter
Switch images between JPG, PNG, and WebP in seconds — conversion happens in your browser, not on a server.
Pick a target format, drop your images, done: PNG screenshots become shareable JPGs, camera JPGs become lean WebP files, and stubborn WebP downloads become PNGs any app will accept. Conversion runs on the Canvas API in your browser, so your files are never uploaded anywhere.
Transparent PNGs converted to JPG land on a clean white background instead of turning black, and a quality slider controls the size/quality trade-off for JPG and WebP. Every file shows its before and after size, so you can see exactly what each conversion saves.

Why use Nofolo’s image converter?
JPG, PNG, and WebP output
Convert any image your browser can open into the three formats the web actually uses.
Transparency handled correctly
PNG transparency is filled with white when converting to JPG — no ugly black backgrounds.
Quality control
A quality slider for JPG and WebP lets you trade a little fidelity for much smaller files.
Batch conversion
Drop a whole folder of images and convert them all in one pass.
No upload — private by design
The Canvas API does the conversion locally; your images never leave your device.
Before and after sizes
A live size comparison for every file shows what the new format costs or saves.
Frequently asked questions
Are my images uploaded during conversion?
No. The conversion happens in your browser with the Canvas API — files never leave your device, which you can verify in the network tab.
How do I convert PNG to JPG without a black background?
This tool fills transparent areas with white automatically when the target is JPG, because JPG has no transparency. If you need to keep transparency, choose PNG or WebP as the output instead.
Should I convert my images to WebP?
For the web, usually yes — WebP files are typically 25–35% smaller than equivalent JPGs and support transparency. Every modern browser has supported WebP since 2020; email clients and older software are the main holdouts.
Can I convert HEIC, AVIF, or GIF images?
Any format your browser can decode works as input: AVIF in all modern browsers, HEIC in Safari, and GIF (the first frame). The output is always JPG, PNG, or WebP.
Does converting reduce image quality?
Converting to PNG is lossless. JPG and WebP re-encode the image, so keep the quality slider at 80+ if you plan to edit the file again — for a final web copy, lower values are usually indistinguishable.
