Export the whole image or layers
Drop a PSD file or click “Choose file”. “Try a sample” shows how it works.
The composite appears on the left. Choose a zoom level and scroll to the part you want to see.
In the layer tree on the right, switch the layer checkboxes and press “Apply visibility and re-composite”.
Press “Save image” to save as PNG, JPEG or WebP. Use “PNG” on a layer, or “ZIP” for all layers.
Save the list as CSV to check layer names, positions, opacity and text in a spreadsheet.
What it does
Opened without sending the file
Reading, painting and export all happen in your browser. The PSD is never sent to a server.
Layer tree and visibility
Shows the group hierarchy and lets you switch each layer on or off, then composite again.
Export single layers
Exports a chosen layer as a transparent PNG, cropped to its pixels or at the full document size.
Reads text and fonts
Lists the text of text layers and the font names used.
ZIP and CSV in one step
Saves all layers in one ZIP, and the layer list as a CSV.
Large files are refused first
Up to 300 MB, 100 million pixels and 2,000 layers. Larger files stop before decoding.
Use cases
- Check the contents of a PSD someone sent you, without special software
- Export part of a design as transparent PNGs for a website
- List layer names and text in a CSV for proofreading
- Turn a PSD you cannot send out into images without uploading it

Privacy & safety
Reading, compositing and export of the PSD all happen inside your browser. Files and images are never sent or stored on a server. Reading runs in a Web Worker, and its code is served from this site.

Image Converter
Choose the target format first, then drop images to convert them in bulk. Tune quality per format, use lossless WebP, set a background for transparency and name the output files — nothing is uploaded.
Image Editor
Annotate a screenshot or photo, reliably hide what must not be seen, tune the colours (black-and-white included) and export — on one screen. Made for how-to guides, bug reports and social posts. Your image is never uploaded and exports carry no metadata.
SVG Studio
Load an SVG file or paste code to get a safe preview and a check of what is inside. Shrink it with SVGO, export PNG or WebP, turn it into a data URI, CSS or React code, and format it — all inside your browser.
Color Converter, Contrast Checker & Palettes (Color Studio)
Type one color and see it in HEX, RGB, HSL, HWB, OKLCH and approximate CMYK. Check WCAG contrast against a background (AA/AAA), generate complementary or triadic schemes and a 50–950 OKLCH scale, preview how a palette looks with color-vision deficiency, and export CSS variables or Tailwind config. Nothing leaves your device.
Image to SVG
Traces a PNG, JPEG, WebP or BMP into an SVG that stays sharp at any size. Best for logos, line art, handwriting and icons. The image is processed only in your browser and never sent anywhere.
AI File Viewer & Exporter
Open an AI file (.ai, Illustrator’s format) in your browser and export it to PNG, JPEG or PDF, with no design software installed. Works with PDF-compatible .ai files. Your file never leaves your device.
