NoFileUpload

Most online file tools ask you to upload your files to their servers.
Sometimes it’s a PDF. Sometimes personal photos. Sometimes office documents with hidden metadata inside.

And honestly, I never liked that.

You upload something sensitive, wait for processing, then just “trust” that the file gets deleted later. Maybe it does. Maybe it doesn’t.

That frustration is the reason I built NoFileUpload.

The idea was simple:

• No uploads

• No accounts

• No tracking

• No servers touching user files

• Everything runs directly inside the browser

The browser has become very powerful now. Using JavaScript, Web APIs, FileReader, Canvas, and local processing, a lot of file operations can happen completely on-device. (NoFileUpload)

So instead of sending files to a backend, NoFileUpload processes them locally on the user’s machine.

Right now the platform has tools for:

• EXIF metadata viewing/removal

• PDF metadata cleanup

• HEIC to JPG conversion

• GPS removal from photos

• Audio/video metadata tools

• Batch processing utilities

• EXIF editing and exporting

• Office file metadata cleaning

and more. (NoFileUpload)

One thing I noticed while building this is how many files contain hidden information people don’t even realize exists.

A normal photo can expose:

• GPS location

• camera model

• timestamps

• device information

PDFs and Office files can contain:

• author names

• company names

• editing history

• software details

Most people share these files without checking anything first.

That’s why privacy-focused browser tools are becoming more common now. A lot of developers are moving toward local-first processing instead of server-side uploads.

Building NoFileUpload was also a fun technical challenge.

Processing files fully in-browser sounds easy at first, but handling large files, memory usage, batch operations, metadata parsing, ZIP generation, and keeping the UI smooth takes real work.

The biggest goal for me was keeping the experience simple:
open tool → drop file → get result.

No signup walls.
No “upgrade to continue”.
No fake limits.

Still improving it every week and adding more tools based on real use cases.

Would genuinely love feedback from other indie hackers:

• What tools would you actually use?

• What privacy concerns do you think most people ignore?

• Would you trust browser-only tools more than upload-based ones?
