PSD to TIFF
Write a PSD out as a TIFF. TIFF has room for more than one image per file, and what lands in this one is the flat composite alone.
Runs on your device. The file is never uploaded.
PSD to TIFF writes the flattened composite as one image directory, big-endian and uncompressed, four bytes for every pixel. TIFF is the one target on this list Photoshop itself uses for layered files, and this writer does not use it that way. The result outweighs the PSD, and nothing inside comes apart again.
Questions
Does PSD to TIFF upload my files?
No. PSD to TIFF runs inside this browser tab, in a Web Worker on your own machine, and no part of your file is sent anywhere. There is no upload step to skip — the tool cannot reach a server even if it wanted to, and the counter on the homepage shows the number of outbound requests the page has made: zero.
How many files can I use at once?
Drop as many as you like. Each file is handled separately and comes back as its own result, so twenty files in means twenty results out.
What can I change about the result?
Nothing to configure — it does one thing, and the result is the same every time you run it on the same input.
Is PSD to TIFF free, and do I need an account?
It is free and there is no account, no sign-in and no quota. Nothing is metered because nothing runs on a server — the only limit is your own device's memory, which is what decides how large a file it can handle.
Does it work offline?
Yes. The whole site is stored in your browser after the first visit, so PSD to TIFF keeps working with the network off. Tools that use a machine-learning model download that model once, on first use, and run offline afterwards.
Can I use PSD to TIFF outside the browser?
Yes. Every tool here is the same code on three surfaces: this page, a CLI command, and an MCP tool an AI agent can call. `psd-to-tiff` is the name it goes by on all three.
