PSD to JNG Converter
FileFlip converts PSD to JNG entirely inside your browser, using ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a PSD file to JNG?#
- Drop your PSD file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to JNG and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the JNG file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting PSD to JNG lose quality?#
Yes, once. PSD keeps everything and JNG does not, so this is the first time the file meets a lossy encoder. At high quality the difference is hard to see, and it is worth keeping the PSD original, because every later re-save of the JNG loses a little more.
Is it safe to convert PSD files online?#
Yes, because nothing is uploaded. FileFlip converts PSD files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What PSD to JNG actually does to the file#
Converting PSD to JNG runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, encodes a lossless source with a lossy encoder for the first time, keeps transparency, and drops EXIF metadata, ICC colour profile, layers and extra images.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: PSD → JNG |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossy, first generation |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| EXIF metadata | Dropped | The target format has nowhere to put it. |
| ICC colour profile | Dropped | The target format has nowhere to put it. |
| Transparency | Kept | Carried through into the converted file. |
| Layers | Dropped | The target format has nowhere to put it. |
| Extra images | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- ImageMagick is asked for a single image, so only the first frame, page, or icon size is read
What is a PSD file?#
A PSD file is Adobe Photoshop's native document format, keeping an image as a stack of independently editable layers, masks, adjustment layers and text objects instead of merging them into a single picture.
Keep a design as PSD while it's still being edited, so layers, masks and adjustment layers stay available for later changes.
Convert PSD to JPEG or PNG once a design is finished and needs to be viewed on the web or by someone without Photoshop, since flattening is what makes it viewable everywhere.
What is a JNG file?#
A JNG file holds a single still image whose colour data is compressed as baseline or progressive JPEG inside the same chunk-based container PNG uses, with an optional PNG- or JPEG-encoded alpha channel for transparency.
There's little reason to create a new JNG file today; the format only makes sense inside an existing MNG animation that already mixes JPEG and PNG frames.
Convert JNG to JPG or PNG for anything meant to display in a browser, since none of the major browsers render JNG natively.
PSD to JNG questions people ask#
What happens to my layers when I convert a PSD to JPEG?
Converting a PSD to JPEG merges every layer into one flat plane, bakes layer masks and adjustment layers permanently into the pixels, and rasterizes any text so it's no longer editable. Paths and guides are dropped entirely, since JPEG has nowhere to store them.
Is a PSB file the same as PSD?
PSB shares PSD's underlying container and specification but sets a different internal version number, which lets a PSB file exceed PSD's 30,000-pixel and roughly 2GB limits. A standard PSD reader can't open a PSB file and vice versa, so the two are related but not interchangeable.
Can I open a PSD file without Photoshop?
Yes. Affinity Photo, GIMP, Krita and the browser-based Photopea all open PSD files, and macOS Preview shows a flattened composite. Full layer, adjustment-layer and text fidelity is most reliable in Photoshop and Affinity Photo; the others vary in how much of the layer structure survives.
Does converting PSD to PNG lose the text layers?
Yes, converting a PSD to PNG rasterizes any text layer into fixed pixels, so the underlying font, size and editable string are gone, leaving only the shape of the letters behind. The text can no longer be selected or edited after that.
