About

Resizes images using 15 social media preset dimensions (Instagram, Twitter, Facebook, LinkedIn, etc.) or custom dimensions with unit selection (px, %, cm, inch). Supports fit modes (cover, contain, fill, inside, outside), batch upload, format conversion (JPEG, PNG, WebP, AVIF), EXIF data toggle, and a target max file size for automatic quality adjustment.

Every platform requires specific image dimensions, and manually resizing each image is time-consuming. This tool provides presets for all major social platforms and batch processing so you can resize an entire photoshoot to platform-specific specs in seconds.

Who should use this tool?

Social media managers preparing images for multiple platforms, developers generating thumbnail variants, and content teams batch-processing images at scale.

Common use cases

Resize a batch of product photos to Instagram square (1080x1080) for an online store
Convert high-res images to Twitter card size (1200x675) with contain fit to avoid cropping
Resize images to a custom width of 800px with auto-height while keeping EXIF data intact
Target a max file size of 100KB and let the tool automatically adjust quality to meet it
Batch convert and resize PNG images to JPEG at 1200px wide for web thumbnails

How to Use

Upload images via drag-and-drop or file browser (supports batch upload)

Select a preset from the 15 social media options or enter custom dimensions

Choose the unit: px for absolute sizes, % for scaling, cm/inch for print

Select a fit mode: cover (crop to fill), contain (fit within), fill (stretch), inside/outside

Pick the output format: JPEG, PNG, WebP, or AVIF

Toggle EXIF data on or off; optionally set a max file size target and click Resize

Examples

Input: 4000x3000 photo with Instagram Square preset (1080x1080) and cover fit. Output: 1080x1080 center-cropped image.

Input: 2000x1500 image with custom 800px width, auto-height, contain fit. Output: 800x600 image with aspect ratio preserved, letterboxed.

Best Practices

Use 'cover' fit for social media presets where you want the image to fill the frame completely
Use 'contain' fit for product photos where cropping would hide important details
Keep EXIF data for photography workflows; strip it for web to reduce file size and remove location data
Use max file size target when uploading to platforms with strict file size limits

Common Mistakes

Using cover fit for images where the subject is at the edge and would be cropped out
Setting a target file size too low, resulting in poor quality; test with one image first
Resizing to cm or inch without setting the correct DPI, resulting in wrong pixel dimensions
Converting from PNG to JPEG and losing transparency without noticing in the preview

FAQ

What are the 15 social media presets? They include Instagram (square/portrait/landscape), Twitter (post/header/card), Facebook (post/cover), LinkedIn, Pinterest, YouTube thumbnail, and more.

Does batch resize preserve filenames? Yes, filenames are kept with a dimension suffix appended.

What does 'max file size target' do? It automatically adjusts JPEG/WebP quality to stay under the specified size.

Can I resize and convert format at the same time? Yes, format conversion and resizing happen in one operation.
