PNG, JPG, WebP, GIF, BMP — converted in your browser. Files never leave your device.
Convert images between PNG, JPG, and WebP without installing anything or uploading your files to a server — the conversion happens entirely in your browser, so your images never leave your device. Drop in one file or a whole batch, pick the output format, and download.
How to use
- Choose the output format (PNG for lossless quality and transparency, JPG for small photo files, WebP for the best size-to-quality ratio on the web).
- For JPG and WebP, set the quality — 80–90% is visually identical to the original for most photos.
- Drop your images onto the tool or click to select them.
- Download each converted file. The size comparison shows what you saved.
Frequently asked questions
Are my images uploaded to a server?
No. This converter runs entirely in your browser using the canvas API — your files never leave your device, which also means there's no file-size limit beyond your device's memory and no privacy risk.
Should I use PNG, JPG, or WebP?
PNG is lossless and supports transparency — best for logos, screenshots, and graphics. JPG is best for photos where small file size matters. WebP typically produces files 25–35% smaller than JPG at the same visual quality and supports transparency, making it the best choice for websites.
What happens to transparency when converting to JPG?
JPG doesn't support transparency, so transparent areas are flattened onto a white background. If you need transparency preserved, convert to PNG or WebP instead.
Can I convert multiple images at once?
Yes — select or drop as many files as you like and they all convert in one pass, each with its own download button. Because processing is local, batch size is limited only by your device's memory, not by an arbitrary server cap.
Does converting reduce image quality?
Converting to PNG is lossless — pixels are preserved exactly. Converting to JPG or WebP is lossy: the quality slider controls the trade-off between file size and fidelity. At 85–90% quality the difference is invisible for typical photos; artifacts appear first around sharp text and hard edges.
What's the maximum file size?
There's no fixed limit. Server-based converters cap uploads (often 25–100 MB) because bandwidth costs money — since this tool never uploads anything, it handles whatever your browser can decode, typically including very large photos.
PNG vs JPG vs WebP: which format should you use?
• PNG — lossless compression, full transparency support, larger files. Best for: logos, screenshots, diagrams, graphics with text, anything you'll edit again.
• JPG — lossy compression tuned for photographs, small files, universal compatibility, no transparency. Best for: photos for email, documents, and platforms that don't accept modern formats.
• WebP — modern format that typically produces files 25–35% smaller than JPG at equivalent visual quality, supports transparency and animation. Best for: websites, where smaller files mean faster loading and better Core Web Vitals.
Rule of thumb: graphics → PNG, photos for compatibility → JPG, anything for the web → WebP. When in doubt, convert a copy and compare the size readout this tool shows you.
Why a browser-based converter is safer
Most online converters upload your image to a server, convert it there, and let you download the result. That means your files travel over the network, sit on someone else's machine, and are subject to whatever their retention policy says — many keep uploads for hours.
This converter uses your browser's built-in canvas engine instead. The file is read locally, re-encoded locally, and downloaded from memory. Nothing is transmitted, so there's nothing to intercept, store, or leak — which matters when the images are contracts, ID documents, product designs, or client work.
The same architecture is why there are no ads, no queue, and no 'premium speed' upsell: there's no server bill to recover.
Common conversions this tool handles
PNG to JPG (flatten screenshots for email and documents), JPG to PNG (prepare photos for further editing), WebP to PNG (make downloaded web images editable in older software), WebP to JPG (maximum compatibility), JPG to WebP and PNG to WebP (shrink images before putting them on your website). GIF and BMP inputs are also accepted and convert to any of the three output formats.
