Convert images between all major formats — JPG, PNG, WebP, GIF, and BMP — instantly in your browser. Adjust output quality for lossy formats, batch convert multiple files, and download results immediately. No files are ever uploaded to a server — conversion is 100% private and happens on your device.
How to Use Image Converter
- 1
Upload your image
Click the upload area or drag and drop your image file. JPG, PNG, WebP, GIF, and BMP are all accepted as input formats.

Choose your target format from the dropdown. Pick WebP for web assets, PNG for transparency, JPG for photos, or GIF for animations.
- 3
Adjust quality (if applicable)
For lossy output formats like JPG and WebP, use the quality slider to balance file size against visual quality. 85% is the recommended default.
- 4
Convert
Click the Convert button. The browser re-encodes the image in the chosen format using the Canvas API — the process is instant for most images.

Quick Reference
About Image Converter
The Image Format Converter converts images between all major formats — JPG, PNG, WebP, BMP, TIFF, GIF, and ICO — in seconds. Different contexts require different image formats: web images need JPG or WebP, logos need PNG transparency, printing workflows need TIFF, and Windows applications need BMP. This converter handles all cross-format conversions in one place without installing any software.
Format conversion is needed when:
- Converting PNG logos to JPG for platforms that don't support PNG
- Converting BMP files (from Windows Paint) to JPG or PNG for web use
- Converting WebP images downloaded from Chrome to JPG for compatibility with older software
- Converting JPG photos to TIFF for professional print workflows requiring lossless source files
- Converting any format to WebP to achieve modern web compression standards
Format conversion is performed using the HTML5 Canvas API's toDataURL() method, which renders the decoded source image and re-encodes it in the target format using the browser's native codec implementations. For formats not natively supported by the browser (TIFF, BMP, ICO), dedicated JavaScript decoder/encoder libraries compiled to WebAssembly handle the binary format parsing and generation. PNG output preserves alpha transparency from source images that have it. JPG output fills transparent areas with white by default (since JPG has no alpha channel).
Input formats: JPG, JPEG, PNG, WebP, GIF, BMP, TIFF, HEIC (via WebAssembly decoder), ICO. Output formats: JPG, PNG, WebP, BMP, TIFF, ICO, GIF. Quality control: adjustable for JPG and WebP output. Batch conversion: convert multiple files at once to the same target format. Transparency handling: preserved for PNG, WebP output; white-filled for JPG output.
All conversion runs in your browser — no files are transmitted to any server. This is the safest and fastest option for format conversion without cloud storage risk. After conversion, you may want to use the Image Compressor to optimize the file size of your converted images before uploading or sharing.
Pro Tips for Image Converter
When converting JPG to PNG for editing, remember that PNG only preserves the current JPG quality — it does not restore lost quality. For best results, always edit from the highest-quality source.
BMP files are completely uncompressed and very large — always convert BMP to JPG or PNG before sharing or uploading to reduce file size by 90%+ instantly.
WebP is the best modern format for web images: 25–35% smaller than JPG at equivalent quality, with full alpha transparency support. Convert all web images to WebP for maximum performance.
When converting to ICO (Windows icon) format, the tool generates all standard icon sizes (16×16, 32×32, 48×48) in a single multi-resolution ICO file — upload your largest source image for best results.
