Corrupt an Image File Online
Corrupt a JPG, PNG or WebP image online for free. Destroys the markers and chunk headers decoders rely on, or produces glitch art at Light level.

Corrompi il tuo file image
Calibrato per .jpg, .jpeg, .png, .webp, .bmp, e funziona altrettanto bene con qualsiasi altro formato.
Perché i file image sono difficili da corrompere per bene
Image formats fail in interesting ways. A JPEG with damaged scan data produces the smeared, glitched look people associate with corruption; a JPEG with a destroyed SOI marker simply will not open at all. You can have either, depending on the level you choose.
Cosa distrugge questo strumento
- JPEG markers. The SOI, SOF, DHT and SOS markers are destroyed, so no decoder can begin a scan.
- PNG chunks. The 8-byte signature plus the IHDR and IDAT chunk headers are overwritten, which also invalidates every CRC.
- WebP and BMP. The RIFF/WEBP chunk headers, or the DIB header for bitmaps, are targeted instead.
- Pixel data. Entropy is scattered through the compressed image data, which is what produces visible smearing at Light level.
Cosa vedrai dopo
| Applicazione | Comportamento |
|---|---|
| Photoshop / GIMP | "Could not complete your request because the file is not compatible." |
| Windows Photos / Preview | "It looks like we don't support this file format." |
| Browsers | A broken-image placeholder is shown. |
| Light level | Often renders as a partly-decoded, glitched image, the classic datamosh look. |
Motivi comuni per farlo
- Testing that an avatar or media upload form validates images properly.
- Producing glitch-art source material at Light level.
- Verifying an image processing library fails safely on malformed input.
- Creating damaged samples for a photo-recovery demonstration.
Come corrompere un file image
- Trascina il tuo file .jpg nel riquadro qui sopra, oppure fai clic per sfogliare.
- Lascia il livello su Standard, a meno che tu non voglia un danno parziale (Light) o debba sconfiggere un software di recupero (Heavy).
- Premi Corrompi file. L'elaborazione avviene sul tuo dispositivo, quindi termina quasi subito.
- Scarica il risultato. Per impostazione predefinita mantiene il nome file e la lunghezza in byte originali.
Domande frequenti su Image
Can I get glitch art instead of a dead file?
Yes. Choose Light. It leaves the structure mostly intact and scatters a small amount of entropy through the scan data, which is what produces the smearing and colour shifts.
Does EXIF metadata survive?
No. EXIF sits in an APP1 segment near the start of the file, inside the header region that gets overwritten.
What about RAW camera files?
RAW formats fall back to the generic binary profile. They break reliably, though the corruption is not tuned to any vendor's layout.
Will the thumbnail still show?
Thumbnails your operating system has already cached may linger, but the file itself no longer decodes.
