What converting an image format changes
The Image Converter re-encodes a picture into a different file format without changing what it shows. Formats exist because they make different tradeoffs between size, quality, transparency, and compatibility, and the wrong one either bloats your page or gets rejected by whatever you are uploading to. This tool reads virtually any common image, decodes it to raw pixels, and writes those pixels back out in whichever of seven formats you select, so there is nothing to install and no format-specific software to hunt down. Results are hosted with a shareable link like any other upload. The one exception is ICO, which downloads directly to your device as a ready-to-use favicon.ico containing 16, 32, 48, and 64 pixel versions.
Which format should you choose
| Format | Strengths | Choose it for |
|---|---|---|
| JPG | Small files, universal support | Photos anywhere, email, print shops |
| PNG | Lossless, transparency | Logos, screenshots, graphics with text |
| WebP | Smallest for the web, transparency | Website images of every kind |
| GIF | 256 colors, legacy support | Simple graphics for old systems |
| BMP | Uncompressed simplicity | Legacy Windows software |
| TIFF | Lossless, professional pipelines | Print production, archiving, scanning |
| ICO | Multi-size icon container | Website favicons |
If the differences between these still feel fuzzy, the image formats explained guide breaks down each one with concrete examples.
Popular format conversions
Jump straight to a guided page for the most common conversions, each with the exact quality and transparency notes for that pair:
- Convert PNG to JPG - shrink a photo, drop transparency
- Convert JPG to PNG - lossless copy for editing
- Convert HEIC to JPG - open iPhone photos anywhere
- Convert WebP to PNG - compatibility with older apps
- Convert WebP to JPG - a standard photo file
- Convert PNG to WebP - much smaller for the web
- Convert JPG to WebP - smaller, same quality
Common conversions
- PNG to JPG: the classic size fix. Photographic screenshots and camera exports saved as PNG shrink enormously with no visible difference.
- Anything to WebP: the modern default for websites, smaller than JPG and PNG at comparable quality and supported by every current browser.
- WebP to JPG or PNG: the escape hatch for older software, print shops, and upload forms that still refuse WebP files.
- JPG to PNG: useful when a system demands PNG, though it cannot restore quality a JPG already lost.
- PNG to ICO: turns a logo into a favicon. For a full multi-size icon set with Apple and Android files included, the favicon generator is the better tool.
- TIFF to JPG: makes scanner and print files small enough to email and preview.
Transparency and quality notes
JPG and BMP have no alpha channel, so transparent regions are flattened when you convert into them; keep transparency by targeting PNG or WebP. GIF output is limited to 256 colors by design, which suits flat graphics and posterizes photographs, so treat it as a compatibility choice rather than a quality one. Lossy targets are written at quality 90, which preserves appearance while trimming size, but converting between lossy formats repeatedly compounds their losses, so always convert from your best original. And if your goal is a smaller file in the same format rather than a different format, reach for the image compressor instead. Converted results follow the standard hosting rules: an instant link unlocked with your free account, and permanent storage in your gallery.
