⚡ 10-second version
Drop your JPGs into tooladda.online/jpg-to-png.html and get PNGs back — one at a time or a whole folder as a ZIP. Converted in your browser, nothing uploaded.
❗ Important
One honest thing first, because it's the question behind most searches for this: converting JPG → PNG cannot recover quality that JPEG already discarded. Read the next section before you convert a hundred photos expecting them to improve.
🎭 What conversion does — and the myth it doesn't fix
JPEG is lossy: when the file was first saved, detail was permanently thrown away. PNG is lossless: it stores exactly what you give it.
So converting a JPEG to PNG stores the JPEG's artefacts, losslessly, forever — and in a much bigger file.
| Before (JPG) | After (PNG) | |
|---|---|---|
| Visual quality | Whatever the JPEG had | Identical — not better |
| Compression artefacts | Present | Present, now permanent |
| File size | Small | Typically 3–10× larger |
| Transparency | Impossible | Possible (but your JPEG had none to restore) |
| Further edits degrade it? | Yes, every save | No |
So when is converting genuinely the right move?
| ✅ Good reasons | ❌ Bad reasons |
|---|---|
| You're about to edit repeatedly and don't want cumulative JPEG loss | "PNG is higher quality so my photo will look better" |
| A tool or platform requires PNG | Trying to undo existing artefacts |
| You need transparency and will cut out the background next | Making a photo archive "better" — you'll just 5× the disk use |
| The image is a screenshot, logo or diagram that should never have been JPEG | |
| Printing workflow demands a lossless source |
That fourth one is the big one: screenshots and logos should be PNG. JPEG artefacts cluster on high-contrast edges, which is exactly what text and line art are made of. If someone sent you a JPEG screenshot, converting it won't repair it — but converting before further editing stops it getting worse.
🧭 How it works
✨ What's inside
| ### 📦 Real batch conversion Drop a folder's worth, get one ZIP. No uploading each file and waiting in a queue. | ### 🔲 Alpha-ready output Real PNG with an alpha channel, so the next step — cutting out a background — has somewhere to put the transparency. |
| ### 🪶 No quality loss from here on Once it's PNG, every subsequent save is lossless. That's the actual reason to convert before editing. | ### 🔒 Entirely local No upload, no cap, no watermark, no signup. |
🛠️ Real jobs
| Situation | Why PNG |
|---|---|
| ✂️ About to remove the background | You need an alpha channel to save into |
| 🖼️ A logo someone sent as JPG | Stop it degrading further; PNG for all future edits |
| 📤 Platform only accepts PNG | Requirement, not preference |
| 🎨 Multiple editing passes ahead | Avoid generation loss on every save |
| 🖨️ Print supplier wants lossless | Common in print workflows |
| 📊 Chart or screenshot for documentation | Text edges stay crisp from now on |

💡 Tip
If the goal is a smaller file for the web rather than a lossless one, PNG is the wrong direction — go to PNG to WebP or the Image Compressor instead. WebP gives you lossless and small.
❓ FAQ
Is it free?
Free, no watermark, no signup, no batch limit beyond your device's memory.
Will converting to PNG improve my photo?
No. JPEG loss already happened and is permanent. PNG preserves what's there — it can't reconstruct what's gone.
Why is the PNG so much bigger?
Because it's lossless. Typically 3–10× the JPEG for a photograph. That's the trade you're making.
Will my JPG become transparent?
No. JPEG can't store transparency, so there was none to carry over. The PNG can hold transparency once you add it — with the Background Remover.
Are my images uploaded?
No — conversion is local to your browser.
Should I use PNG or WebP?
WebP lossless is usually meaningfully smaller than PNG at identical quality. Use PNG when a tool or platform requires it; WebP when you control the pipeline.
🔬 Under the hood
- Decode and re-encode via the browser's own image codecs on a canvas; no server round-trip.
- Batch queued so large sets don't freeze the tab; ZIP assembled client-side.
- Output is real PNG with an alpha channel available.
- Works offline once loaded.
