About Sizeinkb

Sizeinkb is a free collection of online image tools built around one simple idea: compressing an image should take seconds, require no signup, install nothing, and cost nothing.

What We Do

Heavy images slow down websites, fail upload limits and clutter inboxes. Our tools fix that:

• Image file size reducer for JPG, PNG and GIF in one place
• JPEG compressor for photos
• PNG optimizer for logos, icons and screenshots
• GIF size reducer for animations and memes
• Image size reducer in KB for exact KB targets required by forms and portals

Our Principles

• Privacy first – your files are auto-deleted within an hour and never shared.
• Free forever – no accounts, no watermarks, no hidden tiers.
• Simple by design – every tool works in three steps: upload, compress, download.
