This page is for “no stretch” resizing: keep aspect ratio and fit inside limits like 1200×1200 or 1080×1920.

Fit within max dimensions (no stretching, no distortion)

Resize or change image size to stay under a maximum width and height. This is the safest way to resize photos for uploads, websites, and platforms with size limits.

Websites

Fit images within 1200×1200 or 1600×1600 to keep pages fast and consistent.

Social uploads

Fit within 1080×1920 for stories or within 1080×1080 for square uploads without stretching.

Sharing

Keep large camera photos under a max size so they upload faster in email and chat apps.

Limits

Perfect when you’re told: “Max 2000×2000” or “Must be under 1280×720”.

When should you enable padding?

You need an exact output box size
Example: exactly 1200×1200 for a layout — but you don’t want cropping.
You want “no stretch” and “no crop”
Padding keeps the whole image and preserves aspect ratio; it adds background bars.

Frequently Asked Questions

What does “fit within” mean?▼

Fit within (contain) resizes the image so it stays inside a maximum width and height without stretching or cropping. Aspect ratio is preserved.

Will fit-within crop my image?▼

No. Fit-within does not crop. If you need exact dimensions with no bars, you’d typically use a crop tool.

Why is my final image smaller than the max box?▼

Because fit-within preserves aspect ratio. One side may reach the maximum first; the other side becomes smaller to prevent stretching.

What is “Pad to exact box size”?▼

Padding keeps your image un-cropped and un-stretched, but adds background bars so the final output is exactly the box size (for example exactly 1200×1200).

Can I resize JPG, PNG, and WebP here?▼

Yes. You can resize JPG, resize PNG, resize WebP and export to JPG/PNG/WebP. Use PNG or WebP if you need transparency.
