Private by design

Conversion happens on your device — we never see your files.

Advanced codecs

libwebp and MozJPEG WASM — closer to CloudConvert-style results than basic canvas export.

Faster pages

Smaller images are one of the easiest speed wins for small business sites.

How it works

Three steps to a useful result

01

Drop PNG files

Screenshots, exports, or graphics that need JPEG.

Use for email, directories, or legacy tools.

Guide

When PNG to JPG still makes sense

JPEG cannot keep transparency, but it remains the most compatible photo format for email, older portals, and some print workflows. MozJPEG usually beats a basic browser export — pick a solid background before you convert.

These free WebSolNet tools are built for US small business owners — HVAC, auto repair, home services, coaches, and product sellers — who want clear answers without an agency retainer. Run a URL, read the notes, then decide whether to fix it yourself or get a quote.

Practical tips

  • Keep PNG or WebP when you need transparency.
  • For the live website, prefer PNG → WebP over PNG → JPG.
  • Quality 75–85 is usually enough for photos.

Quick FAQ

Will transparency be kept?

JPEG does not support transparency. Choose a white, black, or gray background before converting.

When should I use JPG instead of PNG?

Use JPG for photos. Keep PNG (or WebP) for logos, icons, and graphics that need sharp edges or transparency.

Do you upload my images to a server?

No. Conversion runs in your browser with WebAssembly (libwebp / MozJPEG). Files stay on your device.

Is this free to use?

Yes. No account, no watermark, and no signup required.

Which browsers work best?

Current Chrome, Edge, Firefox, and Safari support the WASM encoders. If WebP encoding fails, the tool falls back to the browser canvas encoder.
