What free software converts JPG to PNG without quality loss?

jpg.now works in any browser with no installation needed. For desktop apps: GIMP (free, cross-platform), IrfanView (Windows), or Preview (Mac) all convert JPG to PNG without reducing quality.

What's free, what costs money

The JPG → PNG tool is free and the free tier is deliberately generous:

  • Guests (no signup): 10 conversions per day, files up to 25 MB each.
  • Free account: 20 conversions per day, files up to 50 MB each.
  • Premium: unlimited conversions, files up to 200 MB, no ads, priority processing.
  • Premium Plus: files up to 1 GB, API access, unlimited everything. See the pricing page for the current price.

Output is never watermarked on any tier. There are no per-conversion fees — you either fit the daily quota or upgrade to remove it entirely.

What counts toward the daily limit

Each completed conversion uses one credit. Things that don't count:

  • Failed conversions (we re-credit them automatically).
  • Re-downloading a file you already converted.
  • Using the in-browser tools (calculators, aspect-ratio, color palette, image-info) — those run client-side and never touch the quota.
  • Cancelling a job before it starts.

The counter resets at midnight UTC. The current state of your quota is always shown in the converter's bottom action bar.

When to upgrade

Most people stay on the free tier indefinitely. Upgrade if any of these apply:

  • You batch-convert dozens or hundreds of files in a single sitting (real estate, e-commerce, photographers).
  • Individual files are over 50 MB (large prints, RAW source files, multi-page PDFs).
  • You want to remove the ads — Premium and above run ad-free.
  • You build something that calls jpg.now from code — the Pro Plus plan unlocks API access with documented rate limits.

Full details on the pricing page. Plans are month-to-month with no contract; cancel any time.
