Resize Image

Resize Image lets you scale down (or up) multiple images at once. You can resize by percentage or by specifying exact pixel dimensions, with full control over output quality and format.

How It Works

Select one or more image files in Windows Explorer.
Right-click and choose FilerFrog → Resize Image.
Choose your resizing method and settings.
Click OK to resize all selected images.

Resize Methods

By Percentage

Scale images to a percentage of their original size. This preserves the aspect ratio automatically. Quick presets are available for common sizes:

25% — Quarter size, ideal for thumbnails.
50% — Half size, a good balance of quality and file size.
75% — Slight reduction, useful for email attachments.

You can also enter any custom percentage value.

By Pixel Dimensions

Specify an exact width and height in pixels. This gives you precise control over the output size, which is useful when images need to meet specific dimension requirements.

Options

Quality — Controls the compression level of the output image. Higher quality means larger file sizes but better visual fidelity.
Convert to JPEG — When enabled, all resized images are saved in JPEG format regardless of their original format. This is useful for reducing file sizes when working with PNG or BMP originals.
Save to separate folder — When enabled, resized images are saved in a new subfolder rather than overwriting the originals. This keeps your original files safe.

Tip: Use the Save to separate folder option when you want to keep the original high-resolution images alongside the resized versions.

Scenario

You need to email 30 vacation photos, but each one is 5 MB. Select all the photos, choose Resize Image, pick the 50% preset, and enable Convert to JPEG. The resized images will be much smaller in file size and ready to attach to an email.

Save as PNG

Check Save as PNG to output images in PNG format instead of the original format. This is useful when you need lossless quality. The PNG and JPEG options are mutually exclusive.

Social Media Presets

The Resize Image submenu includes quick presets for popular social media sizes:

Instagram — 1080 × 1080 (square)
Facebook — 1200 × 630
Twitter/X — 1600 × 900
YouTube — 1280 × 720

Tip: These presets save images as JPEG by default. Use the Custom resize option if you need PNG output for social media.
