About JPG to PNG Converter
JPG to PNG converts JPG photos into PNG format — the lossless image format used for screenshots, design assets, logos, and any image where pixel-perfect quality matters. Upload your JPG, click Convert, and download the PNG. The file picker accepts both .jpg and .jpeg files since they’re the same format under different extensions.
PNG won’t improve the quality of an already-lossy JPG. What it does do is preserve the current state perfectly so further edits and saves don’t compound the quality loss. If you’re going to open the image in a design tool, edit it, and re-save several times, PNG is the right intermediate format — every JPG re-save adds more compression artefacts; PNG re-saves don’t.
When PNG is the right format
For graphics with sharp edges — screenshots, UI mockups, diagrams, logos, line art — PNG is correct. JPG compression introduces visible halos around hard edges and slightly blurs small text. PNG keeps everything crisp. For photos that won’t be edited, JPG is fine and produces smaller files. For anything else, PNG is the safer choice.
The PNG format also supports transparent backgrounds, which JPG doesn’t. If you need a logo or sticker to sit cleanly on a coloured surface, the source needs to be PNG. JPG can’t represent transparency at all — it fills “transparent” areas with white or whatever colour the editor chose at export.
The JPG vs JPEG distinction
There isn’t one — they’re literally the same format. The JPEG (Joint Photographic Experts Group) standard is the technical name, and JPG is the shortened version that survived from older Windows file systems requiring 3-character extensions. Either extension works here, and either decodes to the same image data.
Free, no signup, works on any device.
Frequently asked questions
Three main reasons. First, you need to edit the image and don't want to keep compounding JPG's lossy compression every time you save. Second, you need transparency — for a logo, sticker, or any image that needs to sit on a coloured background. Third, the destination app rejects JPG and requires PNG.
No — but it won't degrade further. JPG uses lossy compression, so detail that was lost during the original save can't be recovered by converting to PNG. What PNG does is preserve the current state perfectly, with no further compression artefacts. If you'll be re-saving the image multiple times (in a design tool, for example), PNG prevents the quality from getting worse with each save.
Only if the original JPG had a defined transparent area, which it cannot — JPG doesn't support transparency at all. To add transparency to a JPG, you need a separate step: convert to PNG first using this tool, then open the PNG in an image editor and remove the background. Or use a dedicated [background remover](/image/image-background-remover) that does both in one shot.
Usually yes, often 3-5× larger. PNG is lossless and JPG is lossy, so PNG has to store every pixel exactly. For photos with lots of gradient detail, PNG files can be quite large — but the trade-off is no quality loss. For screenshots and graphics with flat colours, the size difference is much smaller.
