Common questions
Is SahiSize free?
Yes. Every tool and exam kit is free. There is no login and no pop-up ads.
Is my photo uploaded anywhere?
No. Everything runs inside your browser on your own phone or computer. Your files are never sent to any server. After the first visit the site even works offline.
Where do the sizes come from?
From the exam's official notification wherever we could verify it. Sizes we could only find in secondary sources are clearly labelled “Unverified”. Every exam page links its source and shows the date we last checked it.
What does 20–50 KB mean?
It is the file size the form accepts. The file must be bigger than 20 KB and smaller than 50 KB. Auto-fit aims just under the top of the range, with a safety margin, so the file passes whether a portal counts 1 KB as 1000 or 1024 bytes.
The portal still rejected my file. What now?
Tell us on the report page with the exact error message. We re-check the notice and fix the size quickly.
