To convert PNG to JPG, drop your PNG files into the box above, choose a JPG quality (90 is the default) and a background colour for any transparent areas, then click Convert. Each file is re-encoded as a JPG in your browser and keeps its original name with a .jpg extension. Download the results one by one or all together as a ZIP.
How to use the PNG to JPG tool
- 1
Add your PNG files
Drag PNG images onto the drop area or click to select them. You can add up to 50 files in one run, each up to 50 MB.
- 2
Set quality and background
Move the quality slider between 10 and 100 (90 by default). If your PNGs have transparent areas, pick the colour that should fill them; white is used unless you change it.
- 3
Convert
Click Convert. Your browser decodes each PNG and encodes it as a JPG locally, with no upload step.
- 4
Download
Save each JPG individually, or grab every converted file at once as a single ZIP archive.
PNG vs JPG: when does converting make sense?
PNG is a lossless format. It stores every pixel exactly, supports transparency and is excellent for screenshots, logos, diagrams and anything with sharp edges or flat colour. The trade-off is size: a photograph saved as PNG is often several times larger than the same photo as a JPG, because lossless compression has a hard time with the fine noise and gradients found in real-world images.
JPG uses lossy compression designed for photographs. It throws away detail the eye is unlikely to notice, which makes files much smaller and quicker to email, upload or attach to a form. That makes PNG to JPG a good move when the PNG contains a photo or photo-like content, or when a website, marketplace or application form only accepts JPG.
It is a poor choice for text-heavy screenshots, line art and logos. JPG compression can create soft halos and blocky artefacts around crisp edges, and those graphics usually compress well as PNG anyway. If you need a small file but want to keep transparency, PNG to WebP is a better route than JPG.
What happens to transparent areas?
JPG has no alpha channel, so a transparent PNG cannot be carried over as-is. The converter fills every transparent or semi-transparent pixel with a solid background colour before encoding. By default that colour is white, which suits documents, white web pages and most print uses.
If the image will sit on a dark or coloured background, use the colour picker to choose a matching fill. A logo with soft, anti-aliased edges blends into that colour, so choosing the colour of its final destination avoids a visible light fringe around the artwork.
Why your PNGs never leave your computer
PNG files are often screenshots, and screenshots tend to capture more than intended: open chats, account numbers, internal dashboards, email addresses in a corner of the screen. Uploading them to an unknown conversion server means trusting it with all of that.
Krawly does the conversion with your browser's own image decoder and canvas encoder. The files are read from your disk into the tab's memory, converted there and handed back to you as downloads. Nothing is sent to Krawly's servers and nothing is stored, and closing the tab discards everything. You also do not need an account, and no watermark is added.
Tips for the best results
- Quality 80–90 is a sensible range for photos; drop lower only if file size matters more than fine detail.
- Match the background colour to the page or slide the image will be placed on, especially for logos with soft edges.
- Keep screenshots of text as PNG if they look fuzzy after conversion — JPG is meant for photographic content.
- Converting removes metadata such as camera details and location, which is handy before sharing images publicly.
- Keep your original PNGs: once a file is saved as JPG, the discarded detail and transparency cannot be recovered.
Frequently asked questions
Can I convert PNG to JPG without losing quality?
Not entirely. JPG is a lossy format, so some fine detail is discarded to make the file smaller. At the default quality of 90 the difference is hard to see in photos. Sharp text and line art show artefacts sooner, so check those images before replacing the originals.
What happens to a PNG with a transparent background?
JPG cannot store transparency, so transparent pixels are filled with a solid colour. White is used by default, and you can pick any other colour with the colour picker before converting. If you must keep transparency, convert to WebP instead, which supports it.
Is it safe to convert PNG files here?
Yes. The conversion runs entirely in your browser using JavaScript and the browser's built-in image tools. Your files are never uploaded to Krawly's servers and nothing is stored. When you close the tab, the images and results are gone from memory.
Can I convert many PNG files at once?
Yes. You can add up to 50 PNG files per run, each up to 50 MB. All of them are converted with the same quality and background settings, and you can download them individually or together as one ZIP file.
Is PNG to JPEG the same as PNG to JPG?
Yes. JPG and JPEG are two names for the same image format, so converting PNG to JPEG and PNG to JPG produce the same kind of file. The converter saves results with the common .jpg extension, which every app and upload form recognises.
Will the file names change?
Only the extension changes. A file called banner.png is saved as banner.jpg, so you can easily match converted files to their originals, even when you download a whole batch as a ZIP.
Is converting PNG to JPG online free?
Yes. It is free to use with no signup, no email address, no watermark and no daily limit. Speed depends on your own device, since your browser does the work rather than a remote server.
Private by design. Every Krawly converter runs inside your browser using JavaScript and WebAssembly. Your files are not uploaded, stored or seen by anyone — when you close the tab, they are gone.
