About this tool
Image file size mostly depends on pixel dimensions and compression. This tool handles both in one place. Resize by percentage or exact dimensions, pick an output format, then use the quality slider while watching the preview.
It's the tool to reach for when an upload form rejects your photo, an email bounces for attachment size or a website loads slowly because its images are ten times larger than they display. A phone photo resized to screen dimensions and saved at sensible quality routinely comes out 90% smaller with no visible difference.
How to use it
- Upload an image.
- Resize: set a scale percentage, or type an exact width or height (the other side follows automatically to keep proportions).
- Pick the output format; JPG or WebP for photos you want small, PNG when you need exact pixels or transparency.
- For JPG and WebP, drag the quality slider and watch the preview; 80–85 is the sweet spot for photos.
- Download the result.
Tips
- Resize first, compress second. Shrinking dimensions removes far more bytes than any quality slider, and compression works better on the smaller image.
- For anything viewed on screen, 1,500–2,000 pixels on the long edge is plenty. Email attachments rarely need more.
- Don't scale images up expecting detail; enlarging invents pixels by interpolation; upscaled photos come out soft.
FAQs
How do I get a photo under a specific size, like 2 MB?
Resize to roughly the dimensions it'll be viewed at (say 1,600 px wide), export as JPG at quality ~80, and check. Still too big? Lower the dimensions further before touching the quality slider again.
What quality setting should I use for JPG?
80–85 for almost everything. Above ~90 the file grows fast with no visible gain; below ~60 the damage becomes noticeable in gradients and around edges.
Does resizing lose quality?
Downsizing discards pixels permanently. Keep the original if you may need the full resolution later.
Why is my PNG photo so huge?
PNG stores photos losslessly, which is very inefficient for camera images. Converting the photo to JPG or WebP typically cuts 70–90% before you change anything else.
Is the image compressed on a server?
No; resizing and compression run locally in your browser; even large photos process instantly and privately.
