How many photos can I compress simultaneously in one batch?

Batch limits are aligned with your account tier: Guests can compress up to 5 photos per batch, Free accounts up to 20 photos per batch, Pro accounts up to 100 photos per batch, and Business accounts up to 200 photos per batch. All encoding runs in browser memory with zero network latency.

How does the sequential roll number renaming feature work?

Cyber cafes and coaching centers can enter an exam prefix (such as 'SSC_ROLL_') and a starting number (such as 1001). The tool automatically renames each output photo sequentially (e.g. SSC_ROLL_1001.jpg, SSC_ROLL_1002.jpg).

Can I download all compressed photos together in a single file?

Yes. Once processing finishes, click 'Download All in ZIP' to receive a single organized archive containing all compressed and renamed photos.

Are student photos uploaded to any external cloud server?

No. All resizing, compression, and ZIP generation execute 100% locally on your computer. Student data and applicant photos remain completely confidential.
