Bulk 4:5 Portrait Image Resizer: preset, controls and batch workflow

The 4:5 Portrait Image Resizer standardizes a batch for portrait social posts and mobile-first feed images. Common ratios are useful across social media, video, presentations, photography and print layouts even when the original images have mixed dimensions.

Crop removes edge content to fill the chosen ratio, padding preserves the complete image, and stretch forces the canvas. Preview the intended fit, then export every resized file individually or as a ZIP.

Preset summary: ratio preset: Bulk; output pixels: 1080×1350px. All selected files use the same configuration.

Common questions

Are my images uploaded to a server?

No. Image decoding, canvas processing and file generation happen locally in your browser.

Can I process multiple images at once?

Yes. The same preset is applied to every selected file, and the completed batch can be downloaded as a ZIP.

Which output format should I choose?

JPG is broadly compatible for photos, PNG supports transparent graphics, and WebP usually creates smaller web-ready files.
