The target is preset, so this takes three steps — plus what to expect at 450 KB.
Click upload or drag and drop any JPEG, PNG, WebP, SVG, or GIF file from your device.
This page is preset to 450 KB, so there is nothing to type. Choose JPEG or WebP output for the most efficient result at this size.
Press compress and check the result against your original in the slider. Roughly 2950 × 2950 px is the realistic pixel budget at 450 KB — download when it looks right.
A photo essay can justify 450 KB per image; a sidebar thumbnail cannot. Allocate generously to the images carrying the story and tightly to everything else.
A progressive JPEG paints a rough version quickly and refines it, so a large editorial image feels like it is arriving rather than simply being absent.

What 450 KB is actually for, what it can hold, and how to get there without wasting quality.
450 KB is an editorial allowance. On a long-form feature or photo essay, the images are the reason the reader is there, which changes the calculation — a heavier image is justified when it is the content rather than decoration.
The trade is still real, so it should be spent selectively rather than applied to every image on the site.
Long-form photo essays, magazine-style features, travel and documentary photography, art and architecture pieces, and any page where the imagery is the point.
Photographs remain clean to roughly 2950 × 2950 pixels, or nearly 9 megapixels, which stands up to careful viewing on a high-resolution display.
