How to use Convert Image
- Add your images, including camera RAW, HEIC or TIFF files.
- Choose JPG, PNG or WebP. Pick PNG to keep every pixel exactly (lossless).
- Select Convert images and download each file or a ZIP.
How it works
JPG is best for photos and is supported everywhere. PNG is lossless and keeps transparency, ideal for screenshots, logos and graphics with text. WebP gives smaller files than JPG at similar quality and supports transparency; all current browsers support it.
Camera RAW, HEIC and TIFF. Browsers cannot open these themselves, so the tool loads an open-source decoder on your device when you add one: LibRaw for RAW files (Canon CR2, CR3 and CRW, Nikon NEF, Sony ARW, Adobe DNG, Olympus ORF, Panasonic RW2, Fujifilm RAF, Pentax PEF, Samsung SRW and others), libheif for iPhone HEIC photos and UTIF for TIFF. RAW files are developed at full resolution with the white balance your camera recorded.
Keeping quality. Choose PNG for a lossless result: every pixel of the decoded picture is kept. JPG and WebP at 90–100% are visually identical for photos and far smaller. One honest limit: output is 8 bits per colour channel in sRGB, which is what screens and the web use. A RAW file holds 12–14 bits, so if you plan heavy editing of shadows and highlights, do that in a RAW editor first.
JPG cannot store transparency, so transparent areas are filled with the background colour you choose (white by default). GIF and animated WebP are read as their first frame.
Frequently asked questions
How do I convert CR2 to JPG?
Add the CR2 files, keep JPG selected and choose Convert images. The RAW file is developed on your device at full resolution; the first one takes a few seconds while the decoder loads.
Which camera RAW formats are supported?
Those LibRaw can read, including Canon CR2/CR3/CRW, Nikon NEF/NRW, Sony ARW/SR2, Adobe DNG, Olympus ORF, Panasonic RW2, Fujifilm RAF, Pentax PEF, Samsung SRW, Hasselblad 3FR and Sigma X3F. Very new camera models may not be supported yet; the tool tells you if a file cannot be decoded.
Will converting a RAW file lose quality?
Resolution is kept in full. Choose PNG for a lossless result. Colour depth becomes 8 bits per channel (sRGB), the standard for screens; the extra editing headroom of a RAW file is not carried over.
Can I convert HEIC photos from an iPhone?
Yes. Add the HEIC or HEIF files and choose JPG or PNG. It works in every current browser, not only Safari.
How do I convert PNG to JPG without a black background?
Transparent pixels need a fill colour in JPG. Pick white (default) or any colour under "Background for transparent areas".
Is WebP supported everywhere?
All current major browsers support WebP. Some older desktop software does not, so use JPG or PNG for maximum compatibility.
Are files uploaded?
No. Conversion, including RAW and HEIC decoding, runs in your browser.
Limitations
- Output is 8 bits per channel in sRGB; 16-bit and wide-gamut output are not offered.
- RAW development uses automatic settings (camera white balance, standard tone curve); there are no exposure or colour controls.
- Large RAW files need memory: a 45-megapixel file may not open on a phone.
- Animated GIF and animated WebP become a single frame. Multi-page TIFF: the largest page is used. HEIC bursts and live photos: the main picture is used.
- AVIF and TIFF output are not offered.
