Why convert PNG to JPG?
- Sending screenshots over Gmail or Outlook when the PNG blows past the 25 MB attachment limit.
- Uploading product photos to Shopify, Etsy, or eBay listings that prefer JPG for faster shop pages.
- Posting to Instagram, LinkedIn, or Twitter where oversized PNGs get re-compressed anyway — start from a controlled JPG instead.
- Attaching receipts or documents to SaaS tools (Expensify, Xero, QuickBooks) that reject files over a few MB.
- Embedding photos in Notion, Confluence, or Jira tickets without inflating page load.
- Preparing images for forum posts and classifieds (Craigslist, Facebook Marketplace) where PNG is overkill.
How our converter works
Your PNG is decoded by the browser, painted onto an in-memory Canvas, and re-encoded as JPG at 90% quality. The original file never touches a server — the conversion happens between your file picker and your download folder, which matters when you're handling customer screenshots, internal dashboards, or anything else you wouldn't hand to an unknown third party.

| Compression | Lossless | Lossy (invisible at 85–95%) |
| Transparency | Yes, with full alpha | No — flattened to a solid color |
| Best for | Screenshots, logos, UI | Photographs, email, web uploads |
| Re-editing | Safe to re-save | Quality degrades with each save |
Frequently asked questions
What happens to transparent pixels when I convert PNG to JPG?
JPG has no alpha channel, so transparent areas are flattened to white. If your PNG has a transparent background you want to keep, stay with PNG or convert to WebP instead.
How much smaller will my JPG be?
Typically 3–10× smaller for photographs, sometimes much more. A 12 MB PNG screenshot often lands at 800 KB as a JPG with no visible difference.
Will I lose quality on the conversion?
JPG is lossy, but at 90% quality — our default — the loss is invisible to the human eye. The tradeoff is the massive size reduction. For archival originals, keep the PNG; for sharing, JPG is the right call.
Can I convert many PNGs at once?
Yes. Drop or select multiple files. For batches over three files, the output is offered as a single ZIP download.
Is this safe for confidential screenshots?
Yes. The conversion runs in your browser's memory. We never see the file, never store it, never log it. Closing the tab is all the cleanup needed.
Why do some platforms prefer JPG over PNG for photos?
Smaller files mean faster load times, lower bandwidth bills, and better Core Web Vitals scores. For photographs specifically, the quality difference between PNG and JPG is imperceptible while the size difference is massive.
About the PNG format
PNG (Portable Network Graphics) was released in 1996 as a patent-free successor to GIF. It's the web's default format for anything that needs sharp edges, flat colors, or transparency — screenshots, logos, UI elements, diagrams. Its lossless compression preserves every pixel exactly, which is great for editing and archival but produces files several times larger than an equivalent JPG. For photographs destined for email, social media, or e-commerce listings, converting to JPG is almost always the right trade.
