AI & Media Tools
Pro-level audio, video and image editing without the software or the subscription. Generate AI images from text prompts; remove backgrounds and upscale photos with AI; make compliant passport and ID photos at home; denoise voice recordings, fix lip-sync drift and mix voice-overs with automatic music ducking; split audiobooks and podcasts into chapters; burn subtitles and timestamps into video; scan videos for black frames, dead audio and delivery-spec issues; design YouTube thumbnails, podcast covers and memes; stitch screenshots into one long image; and scrub EXIF and GPS metadata from your media. All processing happens on your device — your photos and recordings are never uploaded.

A pocket studio for audio, video and images
This is ToolNest’s biggest category: forty-one small studio tools that run entirely in your browser. The audio shelf is the deepest — the Karaoke Recorder mixes your voice over a backing track into a finished MP3 or WAV, the Party Mix Maker crossfades a queue of songs into one continuous mix, and the Beat Tag Dropper schedules a producer tag across a beat you are about to share or sell.
For photos, the Passport Photo Maker crops a selfie to official 2×2 specifications and lays out a printable sheet, while the background remover, duplicate-photo finder and screenshot tools handle the everyday image jobs. Video creators get subtitle, thumbnail and hook tools — all local, all private, none of your files uploaded anywhere.
Fresh from the blog: how to make a meme whose top and bottom text actually lands, and how to make a passport photo at home — the sizes, head rules and printing choices that get a home-made photo accepted instead of rejected.
