Guides & Comparisons
Nine free online tools live here, split by what you're working with — photos, audio, video, documents or Discord.
BGNinja removes the background from a photo automatically, leaving a clean transparent PNG for a product shot, a portrait, or a plain white listing photo.
ScanReviver handles the everyday PDF chores — compressing a bloated PDF, merging a few into one, or converting a JPG to PDF and back again.
PicReviver resizes and compresses photos for everyday use, upscales small images, and restores old, faded prints with real face restoration.
StemGrab splits a song into its stems in one click, so pulling out just the vocals — or a clean instrumental — is a single upload away.
ScribeGrab's AI Humanizer rewrites text that reads as AI-generated so it sounds like a person wrote it, alongside its transcription and subtitle tools.
ConvertNinja converts files right in your browser — HEIC to JPG, WEBP to JPG, PNG to SVG and more — without anything ever leaving your device.
Looking for photo tools specifically: BGNinja, PicReviver and PassportNinja between them cover background removal, resizing, upscaling and passport photos, so most everyday photo edits stay a single browser tab away.
What running nine of these side by side has taught us
Nine tools sharing one team teaches you things a single-purpose site never sees. The clearest one: a limit that looks arbitrary from outside is almost always a queue problem from inside. A GPU can only hold one big job at a time, so a video background removal and a photo restoration compete for the same card; the free-tier caps on file size and length exist to keep that queue moving for everyone, not to hold anything back. The tools that run entirely in your browser — resizing, format conversion, the Discord size tool — don't have that problem at all, because nothing leaves your device; that's a deliberate split, not a coincidence, and it's why some jobs feel instant while others show a queue position. The other pattern: people usually arrive already knowing the file type they have and not the tool name for it — "this HEIC won't open" rather than "I need a converter" — which is the whole reason the tool chooser and the grid above are organised by task, not by tool name.
Questions about the tools
What happens to my file?
Your upload is deleted the moment it has been processed, and the cleaned copy is wiped from the server within 45 minutes. Nothing is stored, shared or used to train anything — see the Privacy Policy.
Is it really free?
Yes: no account, no watermark, no daily cap tricks. Advertising is intended to help keep the tools free and the servers running. That's the whole model, here and on every sister tool.
