Are these tools private? Yes — they run in your browser.
Around 29 of the 56 tools run 100% client-side — your file is processed in your own browser and is never uploaded. The AI tools work differently: they send what you give them to an AI provider. This page explains how the client-side tools work, why that matters, and exactly which tools are the exception.
How it works
When you open a tool and add a file, your browser loads that file into memory on your own machine. The conversion, compression, OCR, or edit then runs locally using JavaScript and WebAssembly — the same technology that powers in-browser apps like Figma and Photoshop on the web. The finished result is handed straight back to you for download. At no point is the file transmitted to taimurtools.com or any third party.
How that compares
| TaimurTools | Typical online tools | |
|---|---|---|
| Files uploaded to a server | No | Usually yes |
| Account / signup required | No | Often |
| File-size limits | None (utility tools) | Common on free tier |
| Watermarks | None | Common on free tier |
The exceptions, and how to spot them
A small number of AI features rely on a model that can't run on your device, so they call an external API. These are labelled in the interface so you always know:
taimurtools.com/api.php, which forwards it to Google Gemini, Groq or Hugging Face. AI Summarize PDF and Translate PDF send your extracted text directly from your browser to Pollinations.ai, without passing through this site at all, and the AI Prompt Maker may fall back to the same service. What is sent is not only text — it can include text extracted from your document, reference or source images you upload, and audio or video files. Every tool page carries a panel directly above the tool's controls stating which applies to it. Every file-conversion and editing tool — merge, split, compress, convert, OCR, resize, watermark — is fully client-side.
Frequently asked questions
Are the files I process uploaded anywhere?
It depends on the tool. For around 29 of the 56 — every file-conversion and editing tool — no: your file is read into the page's memory on your device, processed there and handed straight back, and is never transmitted to a server. The AI tools are different: they send what you submit to an AI provider. Each tool page states which applies to it.
Do I need an account or signup?
No. There is no account, no email wall, and no login.
Are there daily limits?
For the 56 file and AI tools, yes: each has a free-tier limit of five runs per day, counted in your own browser and reset at midnight UTC. The allowance is per tool rather than shared, so five merges and five OCR runs on the same day are both available. There are no file-size paywalls on any tool, and TaimurTools Pro lifts the per-tool cap. The calculators for students, teachers and the office have no daily limit.
Which tools are the exceptions that use an online API?
27 of the 56. Around 24 send your input to taimurtools.com/api.php, which forwards it to Google Gemini, Groq or Hugging Face. AI Summarize PDF and Translate PDF send extracted text directly from your browser to Pollinations.ai, and the AI Prompt Maker may fall back to it. Every tool page states which applies, above the tool's controls. Every conversion and editing tool is fully client-side.
How is this different from iLovePDF or Smallpdf?
Most popular tools upload your file to their servers. The TaimurTools conversion and editing tools process files in your browser instead, so those files never leave your device. On limits we are not limit-free either: the free tier allows five runs per tool per day. The difference is that the allowance is per tool rather than shared, there is no file-size paywall on anything, and no signup is required.
