Resizing uses the same free plan limits as conversion: up to 10 MB per file.

Width or height

Set a width, a height, or both depending on the output you need.

Aspect ratio kept

Keep the original proportions automatically to avoid stretched images.

Same format

The output file keeps the same format as the uploaded image.

Dimensions

Why resize an image before publishing?

Oversized images slow down page load, waste bandwidth and hurt search rankings. Resizing to the exact dimensions your layout needs removes unnecessary pixels while keeping the file in its original format.

This image resizer

Morphix resizes images using high-quality resampling so details stay sharp at smaller dimensions. Set a target width, a height, or both. When the aspect ratio lock is on, the missing dimension is computed automatically.

High-quality resampling

What stays untouched

The output keeps the same format as the input: a JPG stays a JPG, a PNG stays a PNG. No hidden conversion, no format switch. The file is ready to drop into your existing pipeline.

Use cases

When should you resize your images?

Resizing is useful whenever the original dimensions exceed what the final medium actually displays.

Web pages Match the image width to your layout breakpoints to avoid the browser downloading more pixels than it renders.
Social media Platforms re-encode uploads to their own specs. Starting from the right dimensions avoids double compression artifacts.
Email Email clients cap display width around 600 px. Sending a full-resolution photo wastes bandwidth and may be clipped.
Thumbnails Generate smaller preview images for product catalogs, galleries or article cards without editing software.
Storage Reducing pixel count shrinks file size. Useful for archives, backups or any context where full resolution is unnecessary.
Print prep Scale images to the exact pixel dimensions required by a print template or specification sheet.
Formats

Supported formats and quality

Morphix supports resizing for JPG, PNG, WebP and AVIF. The output file always stays in the same format as the uploaded image so it fits directly into your publishing or delivery workflow.

Frequently Asked Questions

Does resizing reduce image quality?

Resizing uses high-quality resampling to minimize quality loss. The output keeps the same format as the original.

Can I resize multiple images at once?

Yes. You can upload several images and resize them all to the same target dimensions in a single batch.

Which image formats are supported for resizing?

You can resize JPG, PNG, WebP and AVIF images. The output file keeps the same format as the input.

Will the aspect ratio be preserved?

Yes, if you enable the aspect ratio lock. Setting one dimension automatically adjusts the other to keep proportions.

What is the maximum image size I can resize?

You can upload images up to the file size limit shown on the page. Dimensions can be set up to 12,000 pixels.
