PSD to JPG Converter

A PSD is Photoshop's working file: layers, masks, effects and text. Besides the layers, Photoshop normally saves a flattened copy of the whole picture — the "merged image" — so other programs can show it. This converter reads that merged image directly from the file and saves it as a JPG for email, web pages or clients without Photoshop. It runs in your browser; the PSD never leaves your device.

How to use this tool

1. Drop one or more .psd or .psb files into the box.
2. Set the JPG quality (90% is a good default) and, optionally, a max width.
3. Pick the colour used where the document is transparent (JPG cannot be transparent).
4. Download the JPGs, or all of them as a ZIP.

Formula

Header ("8BPS", version 1 = PSD, 2 = PSB, channels, size, depth, colour mode) → skip colour-mode data, image resources and the layer section by their lengths → merged image data (raw or PackBits run-length rows, one channel after another) → RGB pixels → JPEG at quality q.

RGB, CMYK (stored inverted, converted with R = (1 − C)(1 − K)), Grayscale, Duotone (shown as greyscale), Indexed and Bitmap documents at 8 or 16 bits per channel are read; 16-bit values are rounded to 8 bits. When the document has transparency, Photoshop stores the merged colours matted against white; they are un-matted before the background colour you chose is applied.

Example

A 3000 × 2000 px RGB poster with 24 layers (48 MB) gives a 3000 × 2000 px JPG of the visible artwork, usually a few megabytes at 90% quality. With a max width of 1200, it becomes 1200 × 800 px (2000 × 1200 ÷ 3000 = 800).

If the result is blank or refused

The merged image only exists when "Maximize PSD and PSB File Compatibility" was on when the file was saved; Photoshop asks by default and most files have it. Files saved without it contain layers only, and the page says so. Open the file in Photoshop, turn the option on under Preferences › File Handling, and save again. Lab and 32-bit documents must be converted to RGB 8- or 16-bit first.
