EzySize is a free online image compressor built for the moments when a file is just too big: exam applications, job portals, ID cards, visa forms, and profile uploads that reject anything over a strict KB limit. Instead of guessing with a quality slider, our exact-size tools — compress image to 20KB, to 50KB, to 100KB and to 200KB — automatically find the best quality setting to hit your target size while keeping your photo looking sharp.
Beyond compression, EzySize covers the everyday image tasks people search for: resize an image to exact pixel dimensions for social media or print, convert between JPG, PNG and WebP for the web, crop photos to any aspect ratio with a touch-friendly selector, and combine multiple images into a single PDF for documents and portfolios.
Everything runs 100% in your browser. There is no sign-up, no watermark, no file-size cap, and no server receiving your photos — which makes EzySize a genuinely private alternative to upload-based tools. It works on desktop and mobile alike: Safari on iPhone, Chrome on Android, and every modern desktop browser.
Frequently asked questions
Straight answers — no fine print.
Is EzySize really free?
Yes. Every tool is free with no watermarks, no download limits, and no premium tier. The tools run entirely in your browser, which keeps our costs minimal — so we never have to charge you.
Do my photos get uploaded anywhere?
No. All processing happens locally in your browser with JavaScript. Your files never travel to a server, are never stored, and are never seen by anyone but you.
How do I compress an image to exactly 20KB or 50KB?
Open the exact-size compressor (for example Compress Image to 20KB), drop in your photo, and EzySize automatically finds the best quality setting to hit your target size — handy for exam forms, job portals, and ID applications with strict file-size limits.
Which formats are supported?
EzySize accepts JPG/JPEG, PNG, WebP, and most other common image formats as input. You can convert between JPG, PNG, and WebP, and combine images into a single PDF.
Does it work on iPhone/Android?
Yes. EzySize works in any modern mobile browser — Safari on iPhone and Chrome on Android included. Everything is touch-friendly and no app needs to be installed.
Will compression ruin quality?
Not noticeably. Smart quality reduction typically shrinks files by 50–90% with no visible difference, and you can preview the result and fine-tune the quality slider before downloading.
Do I need to install anything?
No — there is nothing to install and no account to create. Just open the tool you need, drop your image in, and download the result.
