Image Converter — Free JPG / PNG / WebP / BMP
Convert JPG, PNG, WebP, and BMP images in any direction. Drop a batch of files, pick one target format and quality, then download each converted file — all in your browser.
How to convert image formats in your browser
- Drop your images. Drag and drop one or more image files. Multi-select for batch conversion.
- Pick output format. Choose target format: PNG (lossless, biggest), JPG (universal), WebP (smaller than JPG), or BMP (uncompressed).
- Set quality. Use the quality slider for lossy formats. 80% is the sweet spot. PNG and BMP ignore quality.
- Download. Click the download icon on each converted file, or Download All to trigger every finished download at once.
Use Cases
Frequently Asked Questions
Are my images uploaded?
No. Conversion runs entirely in your browser via canvas. Your files never leave your device.
Which format should I pick for the web?
WebP gives the best size-to-quality ratio with near-universal modern browser support. JPG remains the safest choice for maximum compatibility.
Can I convert HEIC?
Use the dedicated HEIC to JPG tool — it handles iPhone HEIC decoding separately for best results.
Will it preserve transparency?
Yes. PNG → WebP preserves alpha. PNG → JPG flattens transparency to a solid background.
Is there a size limit?
No hard limit. Performance depends on your device memory. Tested with 50+ MB images.
Does Download All create a ZIP?
No. Download All triggers an individual download for each converted file rather than bundling them into one ZIP — use the ZIP Creator tool afterward if you want a single archive.
