Convert from JPG - Change a JPG (or WebP) into PNG or WebP.

RepetiGo's convert from JPG tool is a free, browser-based converter that turns a JPG (or a WebP) into a PNG or a WebP file. Upload your image, choose PNG for a lossless copy or WebP for a smaller web-ready file, and download the result. It is the reverse of converting to JPG: here JPG is your starting point, and PNG or WebP is what you get. Everything runs in your browser, so your image is never uploaded to a server.

This is the tool you want when a JPG needs to be a PNG - for a design workflow, a platform that prefers PNG, or a lossless working copy - or when you want to convert a JPG to WebP to shrink it for a website. As an image to png converter it keeps full quality; as a JPG to WebP converter it lets you dial in the quality you need. One honest heads-up up front: converting a JPG to PNG does not add transparency, and we explain exactly why below.

Here is how to convert a JPG to PNG or WebP with RepetiGo. It is a focused, one-file-at-a-time tool, so each conversion is quick and simple.

This tool takes a JPG or WebP as input and gives you PNG or WebP as output. That covers three useful conversions:

If instead you need to go the other way - turning a PNG, HEIC, or WebP into a JPG - that is the Convert to JPG tool, and turning a PNG specifically into a JPG has its own PNG to JPG page. Both are linked below.

PNG is a lossless format, so converting a JPG to PNG gives you a copy with no further compression loss - useful as a working file, for a design tool that expects PNG, or for a platform that asks for it. To convert JPG to PNG here, upload the JPG, choose PNG as the output, and download. There is no quality slider for PNG because PNG is lossless by nature - you get a full-quality copy every time.

A realistic note on file size: because PNG is lossless, a photo saved as PNG is often larger than the original JPG, not smaller. That is normal - you are trading a bigger file for lossless quality and PNG compatibility. If a smaller file is your goal, WebP (below) is usually the better output. This is the straightforward how to convert JPG to PNG answer: pick PNG, download, done - just expect a larger file for photos.

This is the single most common misunderstanding, so here is the clear answer: no. Converting a JPG to PNG does not make the background transparent. A JPG cannot store transparency, so it never had any to begin with - and simply changing the format to PNG does not remove or cut out anything. Your PNG will look identical to the JPG, solid background and all; it is just now in a format that is capable of holding transparency, even though this particular file does not.

If your real goal is a transparent background - a logo with no white box behind it, for example - format conversion is not what you need. You need to actually remove the background, which is a different job done by RepetiGo's Remove Background tool: it detects the subject and deletes everything behind it, giving you a genuinely transparent PNG. So the workflow is: remove the background there to get transparency, not convert here. Converting JPG to PNG is for the format; removing the background is for the transparency.

WebP is a modern format that makes noticeably smaller files than JPG at similar quality, which is why it is popular for websites - smaller images mean faster pages. To convert JPG to WebP, upload the JPG, choose WebP as the output, and use the quality slider (40–100%) to balance size against detail. Higher keeps more detail; lower makes a smaller file. The live preview shows the result so you can pick the sweet spot.

This is a genuinely useful conversion for anyone running a website or blog: swapping heavy JPGs for WebP can cut image weight substantially with little visible difference. The quality slider only appears for WebP output (PNG, being lossless, has no quality setting), so you get fine control exactly where it matters.

The tool also accepts WebP as an input, so you can convert a WebP to PNG. This is handy when you have saved a WebP image from a website and need it in the more universally-supported PNG format for an app, a document, or an older program that does not read WebP. Upload the WebP, choose PNG, and download a lossless PNG copy.

Both are good formats, but they suit different goals. Choose PNG when you want lossless quality, maximum compatibility, or a format that could hold transparency later. Choose WebP when file size matters most - for a website, an email, or anywhere a smaller image helps - and you are happy to trade a little with the quality slider.

Format conversion is a routine job for anyone making websites, handling design files, or preparing images at a print shop or cyber cafe.

RepetiGo converts your image on your own device using the browser's Canvas engine. Your file is never sent to a server, which keeps your images private, works on a weak connection, and means there is no watermark and no account wall. The converted PNG or WebP you download is the full, clean file.

So you know whether it fits before you start, here is what this converter is not built for - and where to go instead.

Upload your JPG, choose PNG as the output format, and download - you get a lossless PNG copy, with no quality slider because PNG is lossless. Expect the PNG to be larger than the JPG for photos, which is normal for a lossless format. If a smaller file is the goal, choose WebP output instead.

No. A JPG cannot store transparency, so it never had any, and changing the format to PNG does not cut anything out - your PNG will look identical to the JPG, background and all. To get a genuinely transparent background, such as for a logo, use the Remove Background tool, which detects the subject and deletes everything behind it.

Upload the JPG, choose WebP as the output, and use the quality slider (40–100%) to balance file size against detail. WebP makes noticeably smaller files than JPG at similar quality, which is great for websites. The live preview shows the result, so you can find the point where the size drops without a visible quality loss.

Yes. The tool accepts WebP as an input, so you can convert a WebP image into a lossless PNG - handy when you have saved a WebP from a website and need a more widely-supported format for an app, document, or older program. Upload the WebP, choose PNG, and download.

It depends on your goal. Choose PNG for lossless quality and maximum compatibility, or a format that could hold transparency later. Choose WebP when file size matters most - for a website or email - using the quality slider to control the trade-off. For photos, WebP is usually much smaller; for graphics you want lossless, PNG is safer.

No - this tool converts one file at a time; there is no batch or ZIP option. Convert an image, download it, then replace the file to do the next one. If you need to process many images, do them individually here, or use the Compress Image tool, which supports multiple files, when your goal is shrinking rather than converting.

The output options are PNG and WebP only. There is no BMP, GIF, TIFF, or ICO output. On the input side, the tool accepts JPG/JPEG and WebP. If you need a JPG as the result instead, use the Convert to JPG tool; if you need a format not offered here, a dedicated converter for that format is the right choice.

Because PNG is lossless. A JPG is already compressed with some quality loss to save space, so re-saving that image as a lossless PNG usually produces a larger file, especially for photographs. That is expected and not a problem - you are gaining lossless quality and PNG compatibility. For a smaller file, choose WebP output instead.

No. The converter runs entirely in your browser using the Canvas engine, so your image never leaves your device - nothing is sent to RepetiGo. That keeps your files private, works on a weak connection, and is why there is no watermark on your converted image.
