About

Websites Acting Picky About File Types? Fight Back with the Rename File Extension on Upload extension! ✊

You crafted the perfect code (.js, .ts), tweaked that config (.yaml, .cfg), or saved essential logs (.log), but NOOOO! The website throws a digital tantrum: "ONLY .TXT FILES ALLOWED!" 😩

Don't let stubborn upload forms dictate your file life! Rename File Extension on Upload is your sneaky sidekick. It intercepts those files right before they leave your browser and whispers sweet .txt nothings into their names. ✨ Poof! ✨ The website is none the wiser, and your upload sails through.

How the Magic Happens:

You Make the Hit List: Head to Options and tell the Renamer which pesky extensions need a .txt disguise (no dots needed!).

Grant Site Access: Visit the picky website, click the Renamer's icon, and hit "Enable on This Site". You're the boss – it only works where you say so!

Upload Like Normal: Select your .ts, .log, or other text-based file.

Instant Makeover: The Renamer swaps the extension to .txt in a flash, locally in your browser. Your original file is untouched!

Awesome Perks:

✅ You Control the List: Rename only the extensions that annoy you.

🔒 Site-Specific Action: Enable the magic only on the websites you choose via the popup.

🚀 "Rename EVERYTHING" Mode: Feeling bold? A toggle lets you slap a .txt ending on any file you upload (use with gusto, or caution!).

👀 Manage Permissions: Easily see and revoke access for sites in the Options page.

In a Nutshell: This extension monitors file selection events on configured websites. When a file is selected for upload, it checks if the file's extension matches your predefined list (or if the "Rename All" option is active). If a match occurs, it creates a modified version of the file object locally with a .txt extension before the browser processes the upload, effectively bypassing website restrictions without altering your original file.
