Most used this month

These are the 8 tools that ran the most jobs over the 30 days up to 24 October 2026, counted from the sites' own job counters. A job is one file or text sent through a tool, so this counts runs, not people. Follow-up steps on a finished result, such as lyrics or a translation, and calls between our own sites are not counted.

Start with the one tool that runs here

Many photos carry a hidden record: the exact coordinates where you stood (when location was switched on for the camera), the time to the second, the camera model and, on some devices, its serial number. Nothing on the picture shows it, and most people only find out when someone else reads it. This page strips that record out and hands the photo straight back.

What comes off: GPS position, date and time, camera make, model and serial, lens, software, and the editing history some programs leave behind. What stays on purpose: the color profile, so the picture does not shift, and the orientation flag, so it does not arrive sideways. The image itself is untouched: the pixels are never re-encoded, only the information blocks around them are rewritten, so there is no quality loss.

It runs on the processor, not a graphics card, and has no daily job limit; at a busy moment a photo can still wait its turn for processor time. A photo can be up to 60 MB; with a pass that goes to 120 MB. JPEG, PNG, WebP, HEIC and HEIF are supported. TIFF deliberately is not: in a TIFF the metadata shares its structure with the image data, and a partial strip that leaves the camera model behind is worse than saying no. Cleaned files are deleted about 45 minutes after you make them.

Guides & comparisons

Each guide lives on the site of the tool it is about: comparisons of free tools, alternatives for services that went paid or shut down, and explainers about how a technique works. These eight are a good place to start; the page behind the link below lists all of them.

Tested by me, with the numbers on the page: What a JPG, PNG and WebP keep: 30 tags tested, The metadata remover tested on JPG, PNG and WebP, Does resizing a photo remove its GPS? Nine operations tested, Does cleaning a photo keep its orientation and color profile?.

About ShinobiTools

What this place actually is

ShinobiTools is one person’s set of tools that share a pass and a set of machines. There is no company floor behind it. The main machine sits in a room with two consumer graphics cards in it, and a few more computers that I also run myself take the other heavy jobs. When a tool here says it removed a background, one of those machines removed it.

That matters more than it sounds. I pay for the hardware once and the electricity monthly, so what I can afford to give away depends on my own costs and not on anyone else’s pricing. The trade-off is fair and worth knowing: the cards are a shared resource, so at a busy moment a heavy job waits.

The plain tools (cleaning pasted text, counting it, converting an image, stripping metadata) are free without a limit and without an account. Anything that costs real machine time has a daily number instead: the GPU jobs, but also the AI rewrite and the image-to-vector conversion, which are capped per day even though they look light. If you need more than that on a given day, a pass is €5 for 30 days or €3 for 24 hours, and the same pass works on every tool in the family rather than only the one you bought it on. I do not sell your files and I do not keep them for later: uploads and results are deleted automatically. The tools work without an account; only buying a pass asks for an email address, so the receipt and the pass have somewhere to go.

Where these tools stop

A tool that lists only what it can do is advertising. Here is the other half, because it saves you the upload.

Background removal is good at a person, a product or an animal against a reasonably separate background. It gets hair against a busy background wrong, and it cannot invent an edge that the photo never captured. Upscaling adds plausible detail, not real detail: a license plate that is four pixels wide stays unreadable, however sharp it looks afterwards. Photo restoration can take out scratches and sharpen soft detail, but it does not correct fading, and a face that has lost its features is gone.

Stem separation needs a mix. A finished studio mix gives the splitter the most to work with; a phone recording of a live room has the room mixed into everything, so expect some of it to come along. Transcription depends on how clear the recording is: when two people talk over each other the words are hard to tell apart, so read the result through and correct it. OCR wants a flat, straight scan at a sensible resolution; a photo of a curved page taken at an angle is where it gives up.

What running twelve sites side by side has taught me

Twelve sites sharing one set of machines teach 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 keep that queue moving for everyone, and they are also what a pass raises.

The tools that run in your browser (resizing an image, converting between common image formats such as HEIC, JPG, PNG and WebP, the Discord size tool) don't have that problem at all, because nothing leaves your device. Video, audio, e-book, camera RAW and image-to-SVG conversions are the exception: they run on the server, with caps on the free tier. 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 organized 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 for most tools the cleaned copy is wiped from the server about 45 minutes later; a few tools hand the result straight back and keep nothing. Passes keep results longer: ScribeGrab and StemGrab keep them 24 hours with a pass, and PassportNinja keeps them 6 hours with the free monthly e-mail pass and 24 hours with a paid pass. There are two exceptions. PicReviver's 3D tools keep the photo and the model for 45 minutes. And there is one optional exception: if you ask ScribeGrab for a clean or subtitled version of your file, it has to keep that upload until the results expire, which is the same 45 minutes (24 hours with a pass). Nothing is shared or used to train anything: see the Privacy Policy.

Is it really free?

Yes: no account, no watermark, and most of my GPU tools give 10 free runs a day, reset at midnight. Advertising and the optional pass pay for the servers.
