WEBPINFO(1)

💖 WEBPINFO(1) — the girlies' guide to peeking inside ur WebP files 💖

okay so bestie, welcome to the General Commands Manual section for webpinfo — she's a command-line girlie from the libwebp universe and she is literally about to spill all the tea about what's actually inside ur WebP files 🔍✨

---

✨ NAME ✨

webpinfo — print out the chunk level structure of WebP files along with basic integrity checks.

like… she shows u the bones of the file AND makes sure nothing's sus. main character energy fr 💅

---

🌸 SYNOPSIS 🌸

webpinfo [-h|-help|-H|-longhelp]

so basically u feed her ur options, then ur files. or u just ask her for help, that works too 🫶

---

🦋 DESCRIPTION 🦋

This manual page documents the webpinfo command. (yes bestie, u are reading a manual page about a manual page situation, it's giving meta 😭)

webpinfo can be used to print out the chunk level structure and bitstream header information of WebP files. She can also check if the files are of valid WebP format — so she's both the gossip and the vibe check 👑

---

🎀 OPTIONS 🎀

• -version — Print the version number (as major.minor.revision) and exit. she tells u what era she's in and then dips 💨
• -quiet — Do not show chunk parsing information. she's keeping it lowkey 🤫
• -diag — Show parsing error diagnosis. when something's wrong she will tell u exactly what's wrong, no cap 🩺
• -summary — Show chunk stats summary. the lil recap slide at the end of the presentation 📊
• -bitstream_info — Parse bitstream header. going deeper than the chunk level, we're in the actual bitstream now 🔬
• -h, -help — A short usage summary. the quick lil "here's how u use me" 🫶
• -H, -longhelp — Detailed usage instructions. the full lore drop, every detail, no crumbs left behind 📚

---

🍓 INPUT 🍓

Input files in WebP format. Input files must come last, following options (if any). There can be multiple input files.

⚠️ bestie listen — the files go at the END. options first, files last. if u flip them around she's not gonna know what u mean and it's gonna be awkward for everyone 💀

and yes, multiple files are allowed. the more the merrier, she can handle it 💜

---

🔥 EXIT STATUS 🔥

If there were no problems during execution, webpinfo exits with the value of the C constant EXIT_SUCCESS. This is usually zero. ✨ (slay, everything worked)

If an error occurs, webpinfo exits with the value of the C constant EXIT_FAILURE. This is usually one. 😭 (not slay, something went wrong)

---

🌈 EXAMPLES 🌈

webpinfo -diag -summary input_file.webp
webpinfo -bitstream_info input_file_1.webp input_file_2.webp
webpinfo *.webp

look at that last one — the glob is eating, she's checking EVERY .webp in the directory. iconic behavior 👑
