Why resize

Oversized dimensions waste bytes.

A 3840px photo displayed at 1920px carries 4× the pixels. Resizing before compressing saves the most.

How resize works

Max W×H, keep aspect

Set max

Enter max width × height — e.g. 1920×1080. Empty means no limit.

Keep aspect

Smaller side scales proportionally. No stretching, no cropping.

Downscale only

Smaller images are left alone. Only larger ones are scaled down.

Resize happens before compression — one pass, same file.

FAQ

Resize — FAQ

Will resizing stretch my image?

No. Aspect is kept. The shorter side scales proportionally to fit within max W×H.

Will small images be upscaled?

No. Downscale only — smaller images are left at original size.

Can I resize and compress together?

Yes. Set max W×H and quality together — one pass, one file out.

Do I need to upload?

No. All resizing is local. No upload, no account.
