JPG, PNG, or WebP images
Processed in your browser - never uploaded
Need a picture in a different format? The Convert Image tool turns any JPG, PNG, or WebP into another of those three formats in a couple of clicks. Whether you're shrinking a photo for a website, swapping a screenshot into a format your software will accept, or flattening a PNG for a document, it handles the job without fuss.
What makes this converter different is where the work happens: entirely inside your own browser. Your image is never uploaded to a server, never queued in the cloud, and never seen by anyone but you. The conversion runs locally using WebAssembly, so even confidential designs, receipts, or personal photos stay firmly on your device.
Each format has its strengths. PNG keeps transparency and sharp edges, JPG is the universal choice for photographs, and WebP produces the smallest files of the three at comparable quality. This page walks you through converting your image and explains the one quirk worth knowing before you start.
Add your image
Drag your JPG, PNG, or WebP file onto the tool, or click to browse and select it from your device. The image loads straight into your browser and stays there, with nothing sent to a server.
Choose the output format
Pick the format you want to convert to: JPG, PNG, or WebP. If you're converting a transparent PNG to JPG, keep in mind that JPG can't hold transparency, so the see-through areas will be filled with white.
Run the conversion
Click convert and the tool re-encodes your image locally using WebAssembly. Larger images take a moment, but everything is processed on your own device.
Download your file
Save the converted image to your device. If you have another picture to convert, just add it and repeat, without any accounts, watermarks, or upload limits.
The whole conversion runs locally through WebAssembly, so your image is never uploaded or stored anywhere. It's the private way to convert sensitive photos, documents, or design files.
Move freely between JPG, PNG, and WebP without hunting for separate converters. Pick the format that suits your destination, whether that's a website, a document, or an email.
Converting to WebP typically gives you the smallest file of the three at similar visual quality, which is ideal for faster-loading web pages and lighter uploads.
There are no accounts, no watermarks, and no daily caps. Convert as many images as you like, straight from your browser.
Most online PDF tools upload your document to a server to process it. This one does not. Every operation runs inside your own browser using WebAssembly, so your files are read, processed, and saved locally - they are never transmitted, stored, or seen by Sapphire Broking or anyone else. That makes it safe to use with financial statements, contracts, and identity documents.
JPG doesn't support transparency, so any see-through areas of your PNG are filled with a solid white background. If you need to keep transparency, convert to PNG or WebP instead.
WebP almost always produces the smallest files of the three at comparable quality. It's the best choice when you want images to load quickly or take up less space.
No. Every conversion happens entirely inside your browser using WebAssembly, so your image never leaves your device and is never sent to us or anyone else.
Yes, the tool converts freely between JPG, PNG, and WebP. Just add your image and pick whichever of the three you want as the output.
PNG is lossless, so converting to it preserves detail, while JPG and WebP use compression that can introduce slight quality loss. For most everyday uses the difference is hard to notice, especially with WebP.
No, there are no limits, accounts, or watermarks. Because the work is done on your own device, you can convert as many images as you need for free.
