Coversharp: Album Art Upscaler

A 200-pixel cover stretched across a lock screen looks like a mosaic. Coversharp is an album art changer built around quality: it finds the covers in your library that need help and repairs them in one tap, square, clean and sharp, then saved back into the songs.

COVER DOCTOR
Coversharp scans the albums stored on your phone and gives every cover a quality score. Clear labels show what is wrong: MISSING, LOW 200px, NOT SQUARE 4:3, BORDERS, PROGRESSIVE, or MIXED when the tracks of one album carry different pictures. Good covers show OK and their real size.

AI UPSCALE ON YOUR PHONE
Tap Enhance and an AI super-resolution model rebuilds the cover at 1080 or 1400 px, and up to 3000 px with Pro. It runs on the device, tile by tile, using the GPU when available. Nothing is uploaded. Drag the before and after divider, hold anywhere to zoom in on real pixels, and set Detail strength if very small lettering looks too invented.

AUTO CLEAN
• Black, white or solid-color borders are detected and trimmed, including letterboxed screenshots with a square cover in the middle.
• A 1:1 crop is suggested from the detail in the picture; drag and zoom to adjust it.
• Pictures that are not square can be cropped, fitted on a soft blurred backdrop, or fitted on a color taken from the image. Covers are never stretched.

FIND THE RIGHT COVER
Use the picture already in the file or in another track of the same album, choose one from your photos, paste one from the clipboard, or search the open MusicBrainz and Cover Art Archive databases by artist and album for the largest version. Only the search text is sent. Coversharp is not affiliated with MusicBrainz or the Cover Art Archive.

LOCK SCREEN AND CAR-SAFE EXPORT
• Lock screen: 1400 × 1400, sharp on modern phones.
• Car-safe: 600 × 600 baseline JPEG under 300 KB, a single front cover and ID3v2.3 for MP3, the combination most car stereos and older players can read.
• Max: 3000 × 3000 (Pro), or a custom size from 500 px.
• Optionally write cover.jpg or folder.jpg into the album folder for players that read folder art.
Before saving, preview the result on a generic phone and car display.

FIX WHOLE ALBUMS (PRO)
Fix several albums or every LOW cover at once. Each album is enhanced once and written to all of its tracks with a single system confirmation. The queue runs in the background and can be canceled at any time.

ALBUM ART STUDIO
Twelve frames drawn by the app: vinyl sleeve, vinyl label, cassette J-card, CD jewel case, 70s stripes, Polaroid, minimal border, torn paper, halftone, duotone, film strip and gatefold. Adjust color and intensity, then embed the square result or save it as an image. Minimal border, Polaroid, vinyl sleeve and CD jewel case are free for everyone.

SAFE BY DESIGN
Works with MP3, FLAC, M4A, OGG and Opus. Each save goes to a temporary copy, is read back and checked, and only then replaces the file. Android asks before any change, and Coversharp never requests access to all files. The original cover of every track is kept on your phone, so Restore original puts it back. Only the cover changes; other details stay as they are.

PRIVACY
Your music and pictures stay on your phone. Upscaling runs offline. No account.
