Overview

Features

It takes the following steps for getting cleaner and safe to use filenames

  • Removes or replace special/international characters that can make your filenames not compliant with servers that don’t have support for international locales and filenames, or third-party services. (e.g. ‘España.png’ will become ‘Espana.png’, ‘prüfen’ will become ‘prufen’).
  • Replaces any ‘+’ in the filename with ‘-‘ (e.g. ‘A+nice+picture.png’ will become ‘A-nice-picture.png’).
  • Replaces any ‘.’ character before the one used for file extension with ‘-‘(e.g. ‘A.nice.picture.png’ will become ‘A-nice-picture.png’).

Works very well out of the box
by Ishko·4 years ago

Very useful and clean, strips every non standard character of all your filenames when uploading. Just activate and forget 🙂
Thanks to the dev for keeping the plugin updated, great job !

Looks Nice but supports Turkish ?
by yasindedo1·6 years ago

If you answer this review i will appreciate it. I dont ask for Turkish translation, as the plugins supports spanish and some other langs then i ask about Turkish. Does the plugin support Turkish characters like ĞİÜÇŞıÖ ?

Muy útil!

Previene problemas con tildes, así como homogeneiza los nombres de archivos que a veces se muestran en el frontend, como con el plugin WP Better Attachments.

Great!
by floydik·8 years ago

This plug-in do exactly what I except and there is no problem with Czech diacritics. If I was uploaded file name “příliš žluťoučký kůň úpěl ďábelské ódy.jpg” I’v got filename: /wp-content/uploads/2017/12/prilis-zlutoucky-kun-upel-dabelske-ody.jpg and Title příliš žluťoučký kůň úpěl ďábelské ódy.
Great job.

Very nice! Only renames filename, not media title :)
by Bjarne Oldrup·8 years ago

As others, I need my filenames to be simple for plugins, backup, different OS’es etc to work without a hiccup, but my title I’d like left alone. So if I choose to upload a file called “Test æøå ÆØÅ +(plus) !(udråbstegn).txt”, I want a sane filename, but the original title where I insert the media… This plugin does that perfectly, where others also changes the title…

Tested with Danish letters, works great 🙂
