🔄 Image Converter
Convert images between PNG, JPG, WebP and BMP formats in seconds. Useful when a site, app or printer requires a specific format. Free, unlimited, private — works entirely in your browser.
How to use
- Upload your image by clicking the upload area or dragging the file in — JPG, PNG, WebP, GIF and BMP are supported.
- Select your target format from the dropdown: JPG for photos, PNG for transparency, WebP for smallest size, or GIF for simple animations.
- Adjust the quality slider if your chosen format supports it (JPG and WebP do; PNG is lossless).
- Click Convert, preview the result, then download your image in the new format.
FAQ
Is it really free?
Yes — every tool on this site is 100% free with no limits, no signup and no watermarks.
Is my data private?
Absolutely. All processing happens locally in your browser. Your files are never uploaded to any server.
Which format should I convert to?
Use JPG for photographs with no transparency, PNG when you need transparency or pixel-perfect graphics, WebP for the smallest file size on modern websites, and GIF only for simple animations. For most web use today, WebP is the best choice.
Will converting change the image quality?
Converting between lossy formats (JPG to WebP) re-compresses the image and can lose a little quality — convert from the highest-quality original you have. Converting to PNG is lossless and preserves every pixel exactly. PNG to JPG discards transparency (transparent areas become white or black).
Can I convert animated GIFs?
The converter processes the first frame of an animated GIF as a still image — animation is not preserved. For animated content, keep the original GIF or convert the animation to a video format instead.
Why is my converted PNG larger than the JPG?
That's normal. PNG is lossless, so it keeps every pixel perfectly — photographic detail that JPG's lossy compression discards. For photos, PNG files are typically 3–5x larger than an 80%-quality JPG. Only use PNG for photos if you specifically need lossless quality or transparency.
Image Converter — Complete Guide
Different situations demand different image formats, and using the wrong one costs you either quality or loading speed. The Image Converter switches your images between JPG, PNG, WebP and GIF in seconds — entirely in your browser, with no uploads and no watermarks.
Understanding the formats
- JPG/JPEG: the universal photo format. Lossy compression keeps files small; no transparency support. Best for photographs and complex images.
- PNG: lossless with full transparency (alpha channel). Larger files, but pixel-perfect. Best for logos, screenshots, graphics and anything needing transparency.
- WebP: Google's modern format — lossy or lossless, with transparency, at 25–35% smaller sizes than JPG. Supported by all modern browsers. Best for web use.
- GIF: 256 colors max, supports simple animation and transparency (1-bit). Best only for tiny animations; outdated for static images.
Common conversion scenarios
PNG screenshots to JPG: screenshots saved as PNG are often several megabytes; converting photos or gradients to JPG at 85% slashes the size. JPG to WebP: the single best optimization for website images — same visual quality, much smaller files. Anything to PNG: when you need to preserve transparency from a WebP or prepare assets for design software that prefers PNG. BMP to JPG: normalize legacy bitmaps into a universally readable format.
Tips for best results
Always convert from the highest-quality source available — every lossy-to-lossy conversion loses a little detail, so avoid chains like JPG to WebP to JPG. If you need transparency, never convert to JPG (it has no alpha channel). After converting to WebP, run the result through the Image Compressor for maximum savings. And remember: the converted file is a new file — your original stays untouched, so you can always try a different format.
Batch conversion strategy
If you're converting many images for a website redesign, work systematically: first convert everything to WebP at 80% quality, then spot-check the results at full size. Any image where WebP introduces visible banding (usually smooth gradients or solid-color graphics) should be redone as PNG instead. Keep a spreadsheet or folder structure noting which format each image uses, so future updates stay consistent. This methodical approach beats converting files one-by-one with random settings.
