Why convert JPG to PNG?
JPEG is the dominant format for photographs because it achieves excellent compression for complex, colour-rich images. But JPEG has one fundamental limitation: it does not support transparency. Every pixel in a JPEG image has a solid colour — there is no concept of a transparent or semi-transparent pixel.
PNG, by contrast, supports full alpha channel transparency. This makes PNG the go-to format for logos, icons, watermarks, cutout images, and any graphic that needs to sit over a different background without a white or coloured box around it. Converting your JPG to PNG is the first step to working with transparency.
Common reasons to convert JPG to PNG
- Creating logos and graphics with transparent backgrounds. If you have a logo or graphic as a JPEG and need to remove the background for use in design work, converting to PNG first is required — PNG is the only standard format that supports transparency for static images.
- Watermarks and overlays. Adding a semi-transparent watermark to photos requires a PNG source file. The converter gives you the PNG you need to work with in your image editor.
- Design composites in Photoshop, Figma, or Canva. Designers often need PNG assets to layer correctly in design tools. Converting a reference JPEG to PNG ensures it can be positioned over other elements without a white background box.
- Preserving quality through multiple edits. JPEG re-encodes the image every time you save, introducing progressive compression artefacts. Converting to PNG and working in PNG format means subsequent saves do not degrade the image further.
- Screenshots and UI mockups. Screenshots of interfaces, dashboards, or app screens often look better as PNG — the lossless compression preserves sharp text edges and flat colour areas without the blurring that JPEG introduces.
- Print production with exact colours. JPEG uses lossy compression that can subtly shift colours. For print work where colour accuracy matters — brand materials, packaging, artwork — PNG's lossless compression preserves exact colour values.

Frequently asked questions
Why would I convert a JPG to PNG?
The most common reason is to enable transparency. PNG supports transparent backgrounds, while JPEG does not. If you need to overlay an image onto a different background — for a logo, a watermark, or a design composite — you need PNG. PNG is also lossless, so it does not introduce further compression artefacts when you edit and re-save.
Will converting JPG to PNG improve quality?
No. Converting a JPEG to PNG does not recover quality lost during the original JPEG compression. The PNG output is a lossless snapshot of the current JPEG — no better or worse in terms of pixel quality. But re-saving it as PNG means future edits and re-saves will not introduce additional JPEG degradation.
Will the PNG file be larger than the JPG?
Yes. PNG uses lossless compression, which means the files are typically 2–4× larger than their JPEG equivalents for photographs. This is the trade-off for lossless quality and transparency support.
Is my image uploaded to a server?
No. The conversion runs entirely in your browser using the Canvas API. Your file never leaves your device.
Can I convert multiple JPGs to PNG at once?
Yes. Drop up to 5 files at once on the Free tier, or unlimited with Pro.
