QUALITY
92% default
Visually lossless. Push to 100% for archival, drop to 80% for size.
What it actually does
02
FLATTEN
Transparency → white matte
JPG has no alpha channel. Morph composites transparent pixels onto white by default. Need a different background? Open in Artboard, fill the layer, export.
04
PRIVACY
Local-only encode
Nothing logged, nothing uploaded. The PNG stays where you dropped it.
How it works
- Open morph.cool in any modern browser — no account, no install, no card.
- Drag the .png onto the drop zone, or pick a folder for batch.
- Pick JPG from the format menu. Set quality if 92% isn't right for the job.
- Morph flattens transparency, encodes via Canvas, saves the JPG to your machine.
- The original PNG is untouched. Nothing was uploaded, nothing was logged.

Why the PNG-to-JPG sites feel awful
The top-ranked compressor built #1 and caps free conversions at 5 MB after forcing an upload to its server before doing anything. The built-in desktop viewer converts one file at a time through three menus. The pattern is the same: server-uploads as the business model, file-size caps as the upgrade lever, and your image as the toll. Morph is the local-only, no-upload version of all of them at the price of a coffee a year.
Where the upload sites still win
If you're on a 2009 Chromebook with 2 GB of RAM converting a 200-megapixel architectural render, the server-side tools will outrun your hardware. They have datacenters; you have a browser tab. For everyone else, that tradeoff lands the other direction.
Frequently asked
How is this different from the converter sites?
The converter sites all upload your PNG to their servers, queue it, cap free conversions by file size (5 MB / 10 MB), and run banner ads. Morph runs the JPEG encoder via Canvas directly in your browser — no upload, no queue, no ad wall, no daily cap.
What happens to PNG transparency?
JPG has no alpha channel — it cannot store transparency. Morph flattens transparent pixels to white by default. If you need a different matte color (black, brand background), open the PNG in Artboard, fill the alpha layer, then export as JPG.
What JPG quality do I get?
Default is 92% quality — visually lossless for most photographic content. Drop to 80% for noticeable file-size savings, push to 100% for archival. Morph never silently downgrades like server-side tools that pre-compress before encoding.
Can I batch a whole folder of PNGs?
Yes. Drop a folder, drop fifty files, drop two hundred screenshots. The free tier has no batch limit. The only constraint is your device's available memory.
Does it work on iPhone or iPad?
Yes — Safari on iOS supports Canvas encoding fully. Drop a PNG, pick JPG, download to Files. The conversion runs locally on your iPhone, never touches a server.
What about the original PNG file?
Untouched. Morph never modifies the source. The JPG is a brand-new file written next to it. Originals stay where you dropped them from.
