What are these tools?
SepoooTools is a set of small, single-purpose tools for the file jobs that come up in everyday life. Each tool does one thing well: one makes a photo smaller in KB, one changes its size in pixels, one joins PDFs, and so on. You do not need to install anything or learn a big program.
How do they work?
Most online tools send your file to a server, change it there and send it back. Our tools work differently. When you open a tool, the page loads a small program into your browser. Your file is read and changed by your own phone or computer, and the result is saved straight to your device.
- Open the tool you need.
- Choose your photo or PDF.
- Pick the size, format or pages you want.
- Download the result. Your original file stays unchanged.
Why use them? The benefits
- Private: your passport photo, payslip or contract is not uploaded anywhere.
- Fast: there is no upload and no waiting in a queue, so small jobs take seconds.
- Free and simple: no account, no watermark, no daily limit, no app to install.
- Made for real forms: the tools are built around the limits that job portals, offices and schools actually use — KB limits, pixel sizes and one-PDF uploads.
- Honest about limits: every tool page explains what the tool can do — and what it cannot.
Which tool do you need?
| Your problem | Use this |
|---|---|
| "File too big" — the limit is in KB or MB | Image Compressor (photo) or Compress PDF |
| The form wants an exact size in pixels | Image Resizer |
| A passport, visa or ID photo | Passport Photo maker |
| Several photos or scans must become one PDF | JPG to PDF, then Merge PDF |
| A scan or photo is sideways | Rotate & Flip or Rotate PDF |
| Only some pages of a PDF are needed | Split PDF or Delete PDF Pages |
| The website does not accept your image format | Image Converter (JPG, PNG, WebP) |
| Many holiday photos are too big to share | Bulk Resize |
| A round profile picture | Circle Crop |
| Someone sent you a Word file and you have no Word | Word (DOCX) Viewer |
Not sure? Type your problem into the tool finder, for example "photo too big" or "one PDF".
What these tools cannot do
We prefer to be clear about limits. Because everything runs in your browser, very large files (hundreds of pages, or dozens of big photos at once) can be slow on an older phone. The tools cannot turn a blurry photo sharp, cannot make a PDF editable like a Word file, and cannot know the exact rules of every office. For official documents, always check the requirements of the office you are applying to.
Questions people ask
Are these tools really free?
Yes. There is no account, no watermark and no daily limit. The site is paid for by the ads you see on the pages.
Are my files uploaded to a server?
No. The tools run inside your browser on your own phone or computer. Your photo or PDF is read and changed there, and the result is saved straight to your device. Nothing is sent to our server.
Do the tools work on a phone?
Yes. Every tool works in a normal mobile browser such as Chrome or Safari. Very large files can be slow on older phones, because your phone does the work.
My form says the file is too big. Which tool do I need?
If the limit is in KB or MB, use the Image Compressor for photos or Compress PDF for PDFs. If the limit is in pixels, use the Image Resizer. Our guide File too big to upload? explains the difference.
Will the quality of my photo drop?
Only as much as needed. Making a file smaller always removes some detail, but for forms and email the difference is usually hard to see. Your original file is never changed, so you can always start again.
Can you guarantee that an office will accept my photo?
No one can promise that. The tools give you the right size and file format, but each office has its own rules for light, background, face position and expression. Always check the official requirements.
Is there a tool for something I need that is not listed?
Tell us on the contact page. We add new tools when many people need the same thing.
