Features
PNG, JPG, and WebP Output
Convert any supported input to JPEG, PNG, or WebP. Choose the format that fits your use case — JPG for photos, PNG for lossless, WebP for modern web use.
Browser-Based
Conversion uses the Canvas API, which runs entirely in your browser. For this tool, your image contents stay on your device.
Adjustable Quality
For JPG and WebP output, control the quality level from 10% to 100%. PNG output is always lossless and ignores the quality setting.
Transparency Warning
If you convert a PNG or WebP with potential transparency to JPG, the tool warns you that transparent areas will be filled with white before you proceed.
Size Comparison
After converting, the tool shows whether the output is smaller or larger than the original so you can make an informed decision.
Instant Download
The converted image downloads directly with the correct file extension for the chosen format.
How Your Privacy Is Protected
The Image Format Converteris built with a privacy-first architecture. Here's how file contents stay on your device — not as a policy, but by how the tool is built.
No file uploads
Your files are processed using browser APIs (Web Workers, Canvas, File API). For this tool, file contents stay on your device.
Local processing only
All computation happens in your browser using your device's CPU. Our servers don't process your file contents.
Works offline
Once the page loads, you can disconnect from the internet and the tool will still work perfectly.
We don't see your files
For this file-processing tool, there's no upload endpoint — files are read and processed entirely by your browser.
Use Cases
Convert PNG to JPG to Reduce File Size
PNGs of photos are often much larger than their JPG equivalents. Converting reduces file size for email, web uploads, and storage without visible quality loss at high quality settings.
Convert to WebP for Web Optimization
WebP files are typically smaller than JPG and PNG at the same visual quality, making pages load faster for visitors on modern browsers.
Convert JPG to PNG Before Editing
If you plan to edit an image and resave it multiple times, converting to PNG first prevents re-encoding quality loss from accumulating across saves.
Strip Transparency for Legacy Systems
Some older software, document formats, or upload systems don't handle PNG transparency correctly. Converting to JPG fills the transparency with white and produces a compatible file.
Save Photos as WebP for Smaller Archives
Convert a folder of photos one at a time to WebP to reduce archive or backup size while maintaining good visual quality.
