What's the PSD maximum size?

PSD is Adobe Photoshop's native document format, in continuous use since Photoshop 3.0 in 1994 and still the universal interchange format for layered raster work across the design industry. Converting JPG to PSD wraps your flat JPEG inside a single-layer Photoshop document that Photoshop, Affinity Photo, GIMP, Krita, Pixelmator Pro, Procreate (read-only), and PaintShop Pro can all open natively. The JPG is placed on the Background layer at the source resolution, and the document inherits the image's pixel dimensions, color profile, and 8-bit depth.

Retouchers, photo editors, and graphic designers convert JPG to PSD when they need to start a layered edit from a flat source file - typically a client-supplied reference photo, a screenshot for compositing, or a final delivery JPG that needs annotation. Once inside the PSD, you can add adjustment layers (Curves, Levels, Hue/Saturation), text layers, smart objects, and non-destructive filters without altering the original pixels. The PSD format supports up to 30,000 x 30,000 pixels and 2GB file size - beyond that you need PSB (Large Document Format).

PSD files are roughly the source JPG size plus 200-500KB of layer overhead when single-layer flat. As you add layers, masks, and smart objects the file grows quickly - a typical 24MP retouching PSD with 30+ layers can reach 500MB-2GB. For final delivery, flatten and convert back to JPG or PNG. For very large canvases see PSB. PSD is also commonly used as a Photoshop-to-After-Effects bridge for motion graphics composites.

Reasons to convert JPG to PSD usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts PSD uploads.
• You need a feature unique to PSD (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that JPG doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the JPG → PSD tool on jpg.now.
2. Drag your JPG file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to PSD. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Open the resulting PSD in Photoshop and immediately convert the Background to a regular layer (double-click) so you can add masks and adjustments non-destructively.
• Add a Curves or Levels adjustment layer at the top of the stack rather than editing pixels directly - PSD's strength is non-destructive editing.
• Set the document color mode to RGB for screen work, CMYK only if heading to commercial print - the conversion creates RGB by default.
• If the PSD exceeds 2GB save as PSB instead - Photoshop will warn you when you cross the threshold.
• Affinity Photo opens and writes PSD with full layer support; GIMP reads PSD with most layer types intact but writes a simplified subset.
