Resize once, ship the right pixels everywhere
Shipping a 4000px photo into a 600px slot wastes bandwidth and hurts Core Web Vitals. Optimagio resizes to the dimensions you actually render, in the same pass it compresses and converts — so the bytes leaving your server match what the browser draws.
- Set width, height, or both; aspect ratio is preserved
- Never upscales beyond native size; edges clamp at 8000px
- EXIF orientation baked into pixels so nothing displays sideways
Real product capability — not a placeholder.
Resizing is the highest-impact image optimization
The single most common cause of image byte debt is serving images far larger than their rendered size. A photo displayed at 600 pixels wide but delivered at 3000 pixels carries roughly 25× the necessary data. Resizing to the real display dimensions usually saves more than any compression tweak.
How Optimagio resizes safely
You provide a target width and/or height; Optimagio scales to fit while preserving aspect ratio. It will not upscale an image beyond its native resolution (which only adds bytes without adding detail), edges are clamped to a maximum of 8000 pixels, and a pixel-count guard protects against malicious decompression bombs. Orientation from EXIF is applied to the pixels so rotated phone photos render correctly.
Practical resizing controls
Width / height
Constrain by width, by height, or both. Aspect ratio is preserved automatically.
No upscaling
Optimagio never enlarges past native resolution, so you never pay bytes for fake detail.
Convert while resizing
Resize and convert to WebP or AVIF in one step for compounded savings.
Bulk normalize
Force an entire catalog to a maximum display size in a single batch job.
Orientation handled
EXIF rotation is applied to pixels, fixing sideways phone photos at the source.
CMYK/ICC safe
Color edge cases are normalized so resized output stays correct across browsers.
Frequently asked questions
Does Optimagio upscale small images?
No. Resizing only ever scales an image down to your target dimensions. Upscaling beyond native resolution adds file size without adding real detail, so Optimagio deliberately avoids it.
Will resizing distort my images?
No. When you set a width and/or height, aspect ratio is preserved automatically so images are never stretched.
What is the maximum size I can resize to?
Edges are clamped to 8000 pixels. Combined with the no-upscaling rule and a decompression-bomb guard, this keeps resizing safe and predictable at scale.
