Compress images to an exact size
Hit any KB limit without killing quality.
Most compressors only give you a vague quality slider. UploadEze lets you set the exact size a form asks for — say “under 50 KB” — and fills that budget with the highest quality it can, shrinking dimensions only if it has to. All of it happens right in your browser.
Target-size mode
Type the KB limit and get a file that fits it — no trial and error with a quality slider.
Best quality that fits
A binary search fills the size budget, so your photo stays as sharp as the limit allows.
Runs in your browser
JPG, PNG and WebP are processed locally with the Canvas API — the image never leaves your device.
How it works
Drop your image or pick it from your device.
Choose “Target size” and enter the KB limit (e.g. 50).
Optionally cap the width in pixels.
Download the compressed file, ready to upload.
Image tools run 100% in your browser. Files sent to our server for PDF operations are processed entirely in memory and never stored.
Common questions
Can it compress a PNG to a tiny size?↓
PNG is lossless, so size mainly follows pixel count. For very small targets the tool reduces dimensions; for photos, JPEG usually hits small KB targets with better quality.
Will my image be uploaded anywhere?↓
No. Image compression runs entirely in your browser — the file never leaves your device.
