How to edit FLAC cover art
- Drop a .flac file into the upload box — the embedded artwork (if any) appears with its dimensions and size.
- To save the current cover as an image, press Extract cover.
- To set new artwork, press Replace / embed new cover and pick a JPEG or PNG.
- Press Download FLAC with new cover — the audio inside is copied bit-for-bit.
This FLAC cover art editor works directly on the file's metadata chain: it parses the FLAC block structure, swaps or inserts the PICTURE block, and appends the original audio frames without ever decoding them. That is the safest possible way to fix artwork in a lossless library — your carefully ripped audio is never touched, and the edit takes a second even on large files. As always on SoundForge, the file stays on your device.
Use it to add missing covers to ripped albums, replace low-resolution thumbnails with proper scans, or pull artwork out of files when the original image is long gone. For the MP3 side of your library — including titles, artists and albums — the Metadata Editor handles full tag editing.
FAQ
Does changing FLAC cover art re-encode the audio?
No. FLAC stores artwork in a metadata block that sits before the audio stream, so this tool rewrites only the metadata chain and copies the compressed audio frames byte-for-byte. The music in the saved file remains losslessly identical to the original.
What image formats and sizes can I embed in a FLAC?
JPEG and PNG are supported, and the image dimensions are detected and written into the FLAC picture block automatically. The format caps a single metadata block at roughly 16 MB, which comfortably fits even high-resolution album scans.
Can I extract the existing artwork from a FLAC file?
Yes — if the file has an embedded picture it is shown as a preview with its dimensions and size, and the Extract button saves it as a standalone JPEG or PNG. Handy for recovering album art you no longer have as a separate image.
Is the FLAC cover art editor free, and are my files uploaded?
It is free with no signup and no limits, and the whole edit happens in your browser's memory — the FLAC is never uploaded to a server. You download the updated file the moment you press save.
