Is this JPEG to PNG converter free?

Yes. Every conversion on Convert Always is free, with no account, no watermark and no daily download cap. The site is funded by advertising rather than subscriptions.

Are my JPEG files uploaded to a server?

No. JPEG to PNG runs entirely inside your browser using WebAssembly, so the file never leaves your device. You can even disconnect from the internet after the page loads.

Can I convert several JPEG files at once?

Yes. Add up to 20 files to the queue, convert them in one pass and download the results individually or bundled into a single ZIP archive.

What is the maximum JPEG file size?

Files up to 100 MB each are accepted. Browser-side conversions are limited mainly by your device's memory, so very large video files convert faster on a desktop than on a phone.

Does it work on mobile?

Yes. The converter is built mobile-first and works in Safari and Chrome on phones and tablets. Heavy media conversions are slower on mobile hardware but still run locally.

What is JPEG?

JPEG is the lossy photographic image format that most cameras, phones and websites default to. It throws away detail the eye is unlikely to notice in order to reach very small file sizes.

Standardised by the Joint Photographic Experts Group in 1992.

Extremely small files for photographs and other continuous-tone images
Adjustable quality, so you can trade sharpness for bandwidth
Opens on literally every device, browser and photo app in use today

What is PNG?

PNG is a lossless raster format built for graphics rather than photographs. Pixels come back out exactly as they went in, and an alpha channel stores per-pixel transparency.

Created in 1996 as a patent-free replacement for GIF.

Perfectly lossless — logos, screenshots and UI mockups stay crisp
Full 8-bit alpha transparency for overlays and layered artwork
Universally supported and safe to re-save as many times as you like

Why convert JPEG to PNG?

PNG is the better fit for screenshots, logos, icons and anything that needs transparency or razor-sharp edges, while JPEG is built for photographs and rich colour images where file size matters more than pixel-perfect edges.
It sidesteps the main drawback of JPEG: no transparency channel — anything transparent becomes solid white or black.
You gain perfectly lossless — logos, screenshots and UI mockups stay crisp.
PNG adds a real transparency channel, so cut-outs and overlays stop picking up a background colour.
Compatibility improves where it counts: Every web browser and operating system and All design tools, office suites and presentation software.

Quality and file size after conversion

Expect the PNG file to be considerably larger. PNG stores everything it is given, so it faithfully preserves the picture JPEG already produced — including any compression artefacts baked in earlier. Converting back and forth cannot restore detail that JPEG discarded.

Compatibility

JPEG opens in Every web browser, Windows Photos, macOS Preview, iOS and Android galleries, Photoshop, Affinity, GIMP, Canva, Office, Google Docs. PNG opens in Every web browser and operating system, All design tools, office suites and presentation software, Print workflows that accept RGB artwork.

If the file has to work for someone else, choose the format their software already understands rather than the one with the best specification.

Limitations to know about

Photographs are typically two to five times larger than the JPEG equivalent
No native animation (APNG exists but support is inconsistent)

When to keep JPEG instead

JPEG is still the right choice for photographs and rich colour images where file size matters more than pixel-perfect edges. Keep the original alongside the converted copy whenever you might need to re-export at a different size or quality — conversion is quick, but recovering discarded detail is impossible.
