Image Converter
10 format converters, each one built for a specific pair rather than a generic drop-down. Pick your source format below. Everything is free, batch-capable, and runs in your browser unless the format makes that impossible.
Convert from JPG
JPG (also written JPEG) has been the default photograph format since 1992. It uses lossy compression tuned for the way human vision works — discarding fine colour detail the eye barely registers — which is why a photo saved as JPG can be a tenth the size of the same image as PNG. The trade-off is that it has no transparency channel and that every re-save degrades the image slightly, so it suits finished photographs rather than working files.
Convert from PNG
PNG is a lossless format built in 1996 as a patent-free replacement for GIF. Nothing is discarded when it compresses, so an image can be opened and re-saved indefinitely without degrading, and it carries a full alpha channel for soft-edged transparency. That fidelity costs space: a photograph stored as PNG is typically several times larger than the same photo as JPG, which is why PNG is the right choice for screenshots, logos and line art rather than camera output.
Convert from WEBP
WebP is Google's 2010 image format, and it is unusual in offering both lossy and lossless modes plus transparency in a single container. In practice it lands roughly 25–35% smaller than an equivalent-quality JPG, which is why it spread quickly across the web once Safari added support in 2020. Its weakness is outside the browser: plenty of desktop software, older phones and printing workflows still will not open a .webp file.
Convert from AVIF
AVIF wraps the royalty-free AV1 video codec into a still-image format, and it compresses harder than anything else in mainstream use — frequently half the size of a JPG at matched quality, with transparency and high dynamic range on top. Browsers decode it well (Chrome since 85, Firefox since 93, Safari since 16.4), but support thins out fast beyond them: many image editors, older operating systems and most print workflows still cannot open one.
Convert from GIF
GIF dates to 1987 and is limited to a 256-colour palette per frame, which is why photographs stored as GIF show visible banding and dithering. It survives for two reasons: it animates, and it is understood by essentially every piece of software ever written. Its transparency is binary — a pixel is either fully visible or fully invisible — so it cannot do the soft edges PNG manages.
Convert from BMP
BMP is Microsoft's original Windows bitmap, and it is usually stored with no compression at all — every pixel written out in full. A 12-megapixel photo as a 24-bit BMP occupies about 36 MB, against roughly 3 MB as a JPG. It still appears in Windows utilities, older scanner drivers, medical and industrial equipment and some embedded systems, which is why converting out of it is a common need even though almost nobody chooses it deliberately.
Convert from JFIF
JFIF is not really a separate format — it stands for JPEG File Interchange Format, and it is the container that the overwhelming majority of files you already call JPGs are stored in. The confusion is purely about the file extension. Certain Windows and Chrome configurations save downloaded images as .jfif instead of .jpg, and although the bytes are a perfectly ordinary JPEG, a surprising amount of software refuses to open them purely because it does not recognise the extension.
Frequently asked questions
Which image format should I convert to?
JPG for photographs that need to work everywhere. PNG when you need transparency or a lossless file to keep editing. WebP when the destination is a web page and you want the smallest file that still supports transparency. AVIF is smaller again but far fewer applications can open it.
Do these converters upload my images?
Almost all of them run entirely inside your browser, so the image never leaves your device. The exceptions are formats a browser cannot decode or encode on its own — HEIC is the main one — and those pages say so directly.
Can I convert several files at once?
Yes. Every converter here accepts a batch: add as many files as you like and they come back as a single ZIP rather than as individual downloads.
Is there a file size limit?
There is no hard limit. Very large or very high-resolution images are handed to our server on most converters, since a browser tab cannot paint a canvas beyond a certain size — a 48-megapixel phone photo hits that ceiling even though it is only a few megabytes. BMP is the exception and always converts locally.
Do I lose quality when converting?
It depends on the target. PNG is lossless, so nothing is lost in that step. JPG, WebP and AVIF are lossy and re-encode the image, though at sensible quality settings the change is not visible. Converting repeatedly between lossy formats does accumulate damage, so convert once from the best original you have.
