Converts a JPG to PNG, WEBP, GIF, or BMP, always at maximum quality — no quality slider on this specific tool.
Introduction
This tool converts JPG or JPEG images into WEBP, PNG, GIF, or BMP — the reverse of a tool like JPG To PNG, but covering four possible target formats from one upload instead of a single fixed pair. If you need a JPG turned into a PDF page rather than another image format, JPG To PDF is a separate tool for that.
How the Conversion Works
Upload a .jpg or .jpeg file, up to 15 MB, then choose a target format. Unlike this site's general Image Converter, this tool doesn't offer a quality setting — every conversion runs at the maximum quality available for whichever format you choose.
What Actually Happens to Image Quality
JPEG compression, defined by the Joint Photographic Experts Group standard, is lossy, and that loss already happened before this tool ever saw the file — a photo from a phone or camera was compressed once, at the point it was saved, and whatever fine detail was lost in that step is already gone. What happens next depends on which format you convert to. Converting to PNG or BMP doesn't add a further lossy step — both are lossless formats, so the already-compressed pixel data is repackaged as-is rather than compressed again. Converting to WEBP does involve a new compression pass, though since there's no quality setting to lower on this tool, it runs at the highest quality available. Converting to GIF is the one target worth a specific warning: GIF can only store up to 256 colors per image, far fewer than a typical photograph contains, so a JPG converted to GIF will usually show visible color banding in gradients and shading that a WEBP or PNG conversion of the same photo wouldn't.
What This Tool Doesn't Do: Fix Orientation
This conversion doesn't read or correct a photo's orientation metadata — the tag some phone cameras save that tells software "rotate this 90° to display it right-side up." If a photo looks sideways in a file browser, it converts exactly as sideways. Rotate it first with Rotate Image if that matters for your result.
What This Tool Doesn't Do: Add Transparency
Converting a JPG to PNG is a common way to get a transparent background — but only if the source image already has one to carry over, and a JPG never does. JPG has no way to store transparency at all, so every pixel in a JPG is fully opaque before this tool ever sees it. Converting that file to PNG changes how the pixel data is stored, but it doesn't add a transparent background that wasn't there to begin with — the result is a PNG with the same solid background as the original JPG, not a see-through one. Removing a background is a separate editing step this tool doesn't perform; it would need to happen before conversion, in an image editor, for the resulting PNG to actually have transparent areas.
What to Check Before You Use the Result
- GIF output means reduced colors. Expect visible banding on photos converted to GIF — this is a limit of the format itself, not a setting you can adjust here.
- Converting to PNG won't add transparency that wasn't already there. A JPG source has no transparent pixels to carry over, since JPG can't store transparency in the first place.
- Sideways photos stay sideways. Rotation isn't detected or corrected automatically; use Rotate Image beforehand if needed.
- Only .jpg and .jpeg files are accepted, up to 15 MB. The upload is checked against the actual JPEG file signature, not just its extension.
- There's no quality control on this specific tool. Every conversion runs at maximum quality for the target format. If you need a smaller file at a lower quality setting instead, Image Converter offers that control.
Converting Several Images at Once
You can queue more than one JPG file in a session, picking a target format for each individually. Once two or more conversions finish, a "Download all" option bundles the completed files together into one ZIP.
Example
A product photo saved as a JPG needs to go on a web page where the background should show through around the product. Converting the JPG to PNG here changes the file format but not what's in it — the background stays exactly as solid as it was in the JPG, since there was never any transparency in the source for the conversion to preserve. Getting an actual transparent background means removing it in an image editor first and saving that result as a PNG; simply converting the existing JPG won't produce it.
FAQs
What can I convert a JPG to with this tool?
WEBP, PNG, GIF, or BMP.
What's the maximum file size?
15 MB.
Will converting reduce my photo's quality?
The JPEG compression already happened when the photo was originally saved. Converting to PNG or BMP doesn't add further compression. Converting to WEBP adds a new compression pass but runs at maximum quality since there's no quality control on this tool. Converting to GIF reduces the image to at most 256 colors, which can visibly affect photos with gradients or shading.
If I convert my JPG to PNG, will it get a transparent background?
No. A JPG file has no transparency to begin with — JPG can't store it — so converting to PNG doesn't create any. The result has the same solid background as the original.
Can I control the output quality?
Not on this tool — conversions run at maximum quality. Use Image Converter if you need a lower-quality, smaller-file option.
My photo looks sideways after converting — why?
This tool doesn't read or correct rotation metadata. Use Rotate Image before converting.
Is my file kept afterward?
No. Files are processed only to complete the conversion and are automatically deleted within 2 hours — see the Privacy Policy for details.
