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 in your browser for this workflow. 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
Image Format Converteris built with a privacy-first architecture. Here's how file contents are handled by the browser-local workflow for this file tool.
Browser-local file processing
Your files are processed using browser APIs (Web Workers, Canvas, File API). For this tool, file contents stay on your device.
Browser-local workflow
For supported file tools, processing happens in your browser using your device's resources. Our servers do not process your file contents for these workflows.
Modern browser workflow
The tools are designed to run in modern browsers, with local processing where supported after the page code loads.
No server-side file processor
For this file-processing tool, files are read and processed by your browser rather than a server-side file processor.
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.
