Question 3

Can I compress images on my smartphone?

Accepted Answer

Yes. SnapReduce works smoothly in mobile browsers on iOS (Safari) and Android (Chrome) without installing external apps.

Question 4

Can I compress a JPEG without losing quality?

Accepted Answer

JPEG is a lossy compression format, which means mathematical rounding removes imperceptible color data. The practical goal is to reduce file size enough while keeping the result visually indistinguishable from the original.

Question 5

Why did my file compress to 96KB instead of exactly 100.0KB?

Accepted Answer

We calibrate our algorithms to target just below your maximum threshold (typically 95KB-99KB) to ensure that strict upload validators with zero tolerance for 100.1KB never reject your submission.

Question 6

Why is my JPEG photo so large originally?

Accepted Answer

High megapixel camera sensors, 100% quality camera presets, detailed textures, and extensive camera EXIF metadata all contribute to bloated file sizes.

Question 7

Are my photos uploaded to any remote server?

Accepted Answer

No. All image operations are executed directly within your web browser's local sandbox memory using HTML5 Canvas. Your personal files never leave your device.

Question 8

Is it safe to compress passport photos and ID cards here?

Accepted Answer

Yes, absolutely. Because no files are uploaded over the internet or stored on cloud disks, your confidential identity documents remain strictly private to you.

Question 9

What is the difference between JPG and JPEG?

Accepted Answer

There is no difference whatsoever. They refer to the exact same image format. The 3-letter extension '.jpg' was created because older MS-DOS operating systems only allowed 3-letter extensions.

Question 10

What happens to transparency when converting PNG to JPG?

Accepted Answer

Because JPEG does not support alpha transparency channels, any transparent background in a PNG will be rendered with a clean, solid white background.

Question 11

Can I convert Apple iPhone HEIC photos to JPG?
