Frequently Asked Questions

Everything you need to know about image resizing

What does reducing image size in KB mean?

It means compressing the file to approach or stay under a target kilobyte (KB) or megabyte (MB) limit—essential for platforms that enforce strict rules, like 'image must be less than 150KB.'

Why reduce image file sizes?

Smaller files upload faster, load quicker on websites, fit email attachment limits, meet application requirements (jobs, visas, government sites), and save storage space.

How does the compression work here?

We prioritize lossless techniques first to shrink the file without quality loss, then apply controlled adjustments if needed for smaller targets. The live preview shows the exact resulting size and quality before you download.

Does compression affect image quality?

Lossless steps preserve quality perfectly. For very small targets, minor adjustments may be required, but the real-time preview lets you find the best balance—you stay in full control.

Will it hit my exact target size every time?

Due to the nature of image formats, it gets extremely close (often exact or slightly under). With the preview and tweaks, it's highly reliable for meeting 'under X KB' requirements.

What are common uses for this tool?

Preparing passport or visa photos, resizing documents for online forms, optimizing images for websites or social media, compressing screenshots for reports, or shrinking email attachments.

How secure is uploading my images?

Extremely secure. You can choose offline client-side processing (nothing leaves your device), or use encrypted server mode where images are never stored long-term or shared with anyone.
