Simultaneously shrink dimensions and compress the file size of your photos in a single action for maximum web optimization.
How to Use Image Resizer & Compressor
Upload your image - the original file size is captured immediately for comparison.
Set the target width and height (in pixels, percent, inches, centimeters, or millimeters), optionally locked to the original aspect ratio.
Drag the compression quality slider and watch the canvas preview and estimated output size update live, then download the result.
Key Features & Practical Use Cases
Preparing a batch of photos for a print shop by setting exact physical dimensions in inches or centimeters while also shrinking the file for faster email delivery.
Getting a product photo to a precise pixel size AND under a strict upload file-size limit in one pass, instead of resizing and compressing as two separate steps.
Scaling a design mockup down by a percentage while dialing in compression quality against a live before/after file-size comparison.
Frequently Asked Questions
Why use this instead of the separate Image Resizer or Image Compressor tools?
This tool applies both changes in a single pass - useful when you need a specific pixel/physical size AND a specific file-size ceiling together, rather than running two tools back to back.
Why does it support inches, centimeters, and millimeters, not just pixels?
Physical units make it easier to target print or layout specs (e.g. a 4x6 inch photo print) without manually converting to pixels first - the tool converts for you against the image's original dimensions.
Is the size shown before downloading accurate?
Yes - it's calculated directly from the actual re-encoded image data on the canvas, so the estimate you see matches the file you download.
