Photo Format Converter
Convert HEIC, RAW, PSD, TIFF, AVIF and JPEG XL locally — one file or a whole folder.
Format conversion is often the least creative part of the job. photos-assemb opens the formats cameras and designers actually produce — HEIC, RAW, PSD, TIFF, AVIF, JPEG XL — and writes the formats clients and the web actually accept.
A single file can be opened in the editor and exported from the File menu. A folder can go through the batch processor with consistent quality, resize and naming, and come back as one ZIP.

What you can do
Format converter, in detail.
Convert HEIC, RAW, PSD, TIFF, AVIF and JPEG XL in your browser. Export JPEG, PNG, WebP, TIFF, AVIF or JXL, individually or as a batch ZIP, without uploading files.
RAW conversion
Turn CR2, CR3, NEF, ARW, DNG, RAF, ORF, RW2 and other RAW files into JPEG, PNG, WebP or 16-bit TIFF.
PSD flattening
Open a PSD/PSB and export a flattened PNG, JPEG, WebP or TIFF for the web or a client.
Modern formats
Decode and encode AVIF and JPEG XL through libvips, with quality controls for the web.
Batch naming
Control the output filename pattern and extension, then download the whole conversion as a ZIP.
No upload
Conversion happens on-device. Confidential client images are not sent to a conversion service.
How it works
From file to finish in three moves.
No install step and no import queue. Open the editor, work on the document locally, and export the file your next tool expects.
Try it now- 1
Add the source
Open one file in the editor or queue a folder in the batch workspace. Mixed formats are fine.
- 2
Choose the target
Pick JPEG, PNG, WebP, TIFF, AVIF or JPEG XL and set quality, resize and sharpening.
- 3
Export or ZIP
Download a single converted file, or process the queue and download one ZIP with predictable names.
Who it is for
Built for real photo work.
These are the workflows the tool is designed around — not a list of theoretical features.
- Converting a folder of iPhone HEIC files to JPEG for a web upload.
- Turning a photographer’s RAW selects into 16-bit TIFF for a retoucher.
- Flattening PSD comps to PNG for a development handoff.
- Preparing AVIF or JPEG XL derivatives for a modern image pipeline.
Questions
Format converter FAQ
Straight answers about formats, privacy and limits.
Can I convert HEIC to JPEG?
Yes. HEIC/HEIF is decoded with libheif WebAssembly and can be exported as JPEG, PNG, WebP, TIFF, AVIF or JPEG XL.
Can I export HEIC?
No. The current libheif build has no HEVC encoder, so HEIC is import-only. AVIF is the available modern alternative for efficient delivery.
Are metadata and colour profiles preserved?
The conversion pipeline focuses on pixels and does not guarantee full EXIF/IPTC preservation. CMYK output uses ICC profiles; standard web exports are sRGB-oriented.
Can I convert many files at once?
Yes. The batch processor accepts mixed formats and writes a single ZIP. Very large folders are limited by available browser memory.
