WHY CONVERT
Why convert HDR to PSD
02
Acceptance by downstream tools
PSD is the format most receiving systems expect for this kind of content. Converting upstream avoids the rejection and silent re-encoding that often happen when HDR reaches an unprepared pipeline.
03
Portable, predictable file format
PSD is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.

QUALITY & FIDELITY
Quality and fidelity
- Lossless to lossless: conversion is mathematically reversible in principle.
- Target supports alpha but the source has none, so the output is fully opaque.
- Metadata is dropped: the target format does not carry it natively.

— FAQ
Frequently asked.
Is HDR to PSD conversion free?
Yes. LocalConvert is completely free, with no signup and no per-file or per-day limits.
Do my files get uploaded anywhere?
No. HDR to PSD conversion happens entirely inside your browser using WebAssembly — your file never leaves your device.
What's the maximum file size?
There's no fixed cap — the practical limit is your device's available memory. Very large files may take longer or fail on low-RAM devices.
Does it work offline?
Yes — once the page has loaded, HDR to PSD conversion works without an internet connection. Re-open the page once to cache it.
Will conversion preserve quality?
LocalConvert uses the industry-standard tools (FFmpeg, ImageMagick, Pandoc) — quality matches what professionals use on the command line. Lossy formats will still lose some quality on each re-encode.
