Where to start
If you have a folder of mixed images, start with the Image Converter: add JPG, PNG, WebP, AVIF and BMP files together, keep ticked the ones you want in this round, and choose PNG, JPG or WebP as the output. Your files stay in the workspace after an export, so you can export again in another format without adding them twice.
If you arrived with one specific job — say, a WebP that has to become a PNG — the conversion pages below open the same workspace with the output already chosen, and their explanations focus on that one question.
How these tools run
Each tool is a normal web page. When you add files, the browser decodes them with the same image engine it uses to display pictures, redraws them in the output format and hands you the result as a download. The image bytes are not sent to a server to be converted, so there is no upload queue, no quota and no server copy to delete.
Because the work is local, the practical limit is your device rather than a rule set by the tool. A phone with little free memory will struggle with a batch of very large photographs long before any file count matters; converting in smaller groups usually helps.
PNG, JPG and WebP: what actually differs
- Converting to PNG never loses image detail, but the file can grow.
- Converting to JPG always loses some detail, and the loss is permanent in the new file.
- Converting to WebP often gives a smaller file, but it is not guaranteed — small or flat images can grow.
- No conversion can bring back detail that a JPG already discarded.
PNG is lossless and supports transparency. Every conversion to PNG reproduces the pixels exactly, and a transparent background stays transparent. That makes it right for logos, screenshots and images you will keep editing — and large for photographs.
JPG (identical to JPEG — two names for one format) is lossy and has no alpha channel. It discards detail to save space and cannot store transparency, so exporting to JPG asks you for the colour that fills transparent areas.
WebP sits in between: it has a quality setting like JPG and keeps transparency like PNG, and for photographs it is usually the smallest of the three. WebP export depends on your browser, and there is no lossless WebP option here.
Current limitations worth knowing
- Metadata is not carried over. EXIF fields such as camera model, capture date and GPS coordinates are not written into the converted file; a photo stored sideways is exported upright instead. Keep the original if you need that information.
- Animated WebP produces a single frame. The converter draws one still image; it does not export an animation or a frame sequence.
- Colour profiles are not preserved. Wide-gamut images are converted through the browser’s normal display pipeline.
- WebP export depends on your browser. The page checks your browser when it loads; if WebP cannot be encoded, the option is marked unavailable rather than quietly swapped for another format.
- Very large batches are limited by device memory, not by a rule imposed by the tool. Files are processed one at a time so memory use stays predictable.
Questions
Are my images uploaded anywhere?
No. Every image tool on this page decodes and re-encodes files inside your browser. The image bytes are never sent to a server, and there is no server-side copy to delete afterwards.
Which conversion should I pick?
Pick PNG when you need transparency or an exact copy — logos, screenshots, anything with a cut-out background. Pick JPG when the image is a photograph and the place you are sending it expects JPG. Pick WebP when file size matters and transparency still has to survive. If one folder holds several of these cases, start with the Image Converter.
Will converting to JPG always make the file smaller?
Usually, but not always. JPG compresses photographic detail very efficiently, while flat graphics with large areas of solid colour are exactly what PNG is best at. A simple diagram can come out larger as a JPG — and look worse. If size matters, compare the downloaded file with the original.
Can these tools fix a blurry photo?
No. Detail that a JPG discarded when it was first saved is gone for good, and changing the format does not rebuild it. What a conversion can do is stop further damage — for example, moving an image to PNG before you edit and re-save it many times.
Which formats are supported?
The Image Converter opens JPG (including JPEG and .jfif), PNG, WebP, AVIF and BMP, and exports PNG, JPG and WebP. AVIF and BMP can be opened but not exported, and HEIC is not supported.
