Question 1

Do I need to upload my files?

Accepted Answer

For tools that run in your browser, no. Your file is processed on your device instead of being sent to a server. The tool will tell you if a particular feature works differently.

Question 2

Are these tools really free?

Accepted Answer

Yes. GainUtility is built around free, useful browser tools without requiring an account just to do a simple task.

Question 3

Will compressing my file make it look worse?

Accepted Answer

It depends on the tool and the format. Image compression can trade some quality for a smaller file, while other tools can reduce size with little visible change. We show the relevant settings before you process the file.

Question 4

Can I use GainUtility on my phone?

Accepted Answer

Yes. The tools are designed to work in modern mobile and desktop browsers. For larger files, performance can depend on your phone or computer.

Question 5

What happens to my file after I use a tool?

Accepted Answer

For browser-based tools, processing happens locally on your device, so there is no normal upload step. If a tool needs server-side processing, its interface should clearly tell you.

Question 6

Do I need to create an account?

Accepted Answer

No. You can use the tools without creating an account.

Question 7

Why is a tool slower on my phone?

Accepted Answer

Some tools do the work directly on your device. Large PDFs, images or complex files can therefore take longer on a phone than on a desktop.

Question 8

Why didn't my file get smaller?

Accepted Answer

Some files are already compressed, so there may not be much room to reduce them further. Try another compression setting or format if the tool provides one.
