Overview
File formats are the dialects of the image world, and not every program speaks every dialect. A design tool exports PNG, a client insists on JPG, a content system recommends WebP, and somewhere in the middle stands a person renaming file extensions and hoping for the best — which does not work, because the data inside has to be genuinely rewritten. This converter does that rewriting properly: it decodes your picture, paints it onto a canvas, and encodes it again in the format you picked.
The whole exchange happens inside the tab you are reading. That matters more than it might sound, because conversion sites are exactly the sort of place people upload screenshots full of account numbers, half-finished designs and family photos. Here there is no upload at all, so a sensitive image is no riskier to convert than an anonymous one.
What is the difference between PNG, JPG and WebP?
PNG is the careful archivist of the three. It stores images losslessly, keeps text and edges razor sharp, and supports transparency — which is why logos, screenshots and diagrams live there. The price is weight: a photograph saved as PNG can be ten times heavier than it needs to be. JPG is the long-serving traveller's format, understood by every device and program on earth. It compresses photographs brilliantly by discarding detail the eye barely misses, but it cannot do transparency and it softens crisp edges.
WebP is the modern compromise, built specifically for the web. At the same visual quality it typically produces noticeably smaller files than JPG, and unlike JPG it can hold transparency like PNG. Its one weakness is reach: a few older programs and some desktop tools still refuse to open it, which is exactly why a converter like this one exists in both directions.
Features
- Three formats, every direction: PNG, JPEG and WebP can each be the source or the destination, including WebP back to the classics.
- Source report: the panel names the format and size you started with, so the conversion is never a mystery.
- Quality control: a slider for JPEG and WebP output lets you trade a little fidelity for a lot of kilobytes.
- Size comparison: converted weight and the difference from the original are shown before you download anything.
- Correct filenames: the download carries the right extension for its new format automatically — no renaming rituals.
- Transparency handled honestly: converting to JPEG paints see-through areas white instead of inventing a colour, and the page tells you it happens.
- No uploads, no accounts: the file is decoded and re-encoded by your own browser, start to finish.
Benefits
- Compatibility on demand: whatever a form, client or program demands, you can supply it in seconds.
- Smaller web images: moving photographs to WebP trims page weight without changing a single pixel's position.
- Privacy for real documents: screenshots of statements, IDs-in-progress and unreleased work stay off strangers' servers.
- Zero learning curve: there is nothing to configure beyond a format and, if you care, a quality number.
- Free and unlimited: convert one file or fifty, one at a time, without a plan or a watermark appearing anywhere.
Who can use it
Designers handing assets to developers who asked for WebP, shop owners whose supplier sent PNGs the size of posters, students whose portal accepts only JPG, and anyone sent a WebP by a browser who then discovered their favourite editor will not open it. Format friction shows up everywhere; this page is the small wrench for it.
How to use
- Drop your image onto the panel, or click and choose a file from your device.
- Check the source report so you know the format and size you are starting from.
- Pick the destination format — PNG, JPEG or WebP.
- If you chose JPEG or WebP, set the quality; 90 is a safe default for photographs.
- Compare the converted size with the original and glance at the preview.
- Download the converted file, already named with the correct extension.
Frequently asked questions
Does converting a JPG to PNG improve its quality?
No. Conversion cannot restore detail that an earlier lossy save already discarded. The PNG will faithfully preserve the picture exactly as it is now — softness included — and will usually be a much larger file for its trouble.
Why does the converted photo sometimes look different?
If the destination is JPEG or WebP at a modest quality setting, the encoder discards fine detail, which can soften textures. Raise the quality slider towards 95–100 and the difference becomes very hard to see.
What happens to transparency when I convert to JPEG?
JPEG cannot store transparency, so transparent pixels are painted onto a white background during conversion. If you need the see-through areas preserved, convert to PNG or WebP instead.
Can I convert an animated image?
The canvas holds a single still frame, so an animated GIF or WebP becomes a picture of its first frame. For moving images you would need a dedicated animation tool.
Is the camera and location data kept?
No. The converted file is built fresh from pixels alone, so EXIF metadata — camera model, timestamps, GPS coordinates — is not carried across. Many people find that reassuring when sharing photos publicly.
Which format should I choose for a website?
WebP for photographs and most graphics, since it is compact and supports transparency; keep a JPG version if you must support very old software. PNG remains the right call for crisp screenshots and logos that are already small.
Conclusion
Formats should never be the reason a job stalls. Pick the dialect the other side speaks, check the size, and download a properly converted file — converted by your own browser, with the original never having left your hands.
