About this tool

Social Media Image Resizer applies common publishing pixel presets for Instagram, LinkedIn, YouTube, X/Twitter, Facebook, Discord, and WhatsApp. Choose a preset, drop an image, and download the resized file. Presets are UtilBloom starting sizes for everyday posts—confirm current recommendations in each platform’s help centre before campaign launches, because networks change specs.

How to use

Step 1

Open Social Media Image Resizer under Images.

Step 2

Pick a platform preset (for example Instagram post or YouTube thumbnail).

Step 3

Drop or choose an image from your device.

Step 4

Process and download the resized image.

Step 5

Spot-check safe zones and file size in the destination app before publishing.

How it works

Each preset fills width and height for using common pixel targets already used across UtilBloom’s former per-platform pages. Cropping and cover behaviour follow the shared image resize engine. Platforms may still letterbox, crop profile circles, or recompress uploads—always preview in the native composer.

Worked example

Square Instagram post

Input: Preset: Instagram post 1080×1080; source photo from device
Output: Downloaded JPEG/PNG at the selected preset size
Walkthrough: Select Instagram post, drop a landscape photo, process, then open the download and confirm 1080×1080 before uploading.

Limitations

Preset pixels are starting points, not a live scrape of platform help docs.
Safe zones and UI chrome differ by app and device.
File-size limits and codecs are enforced by each network after upload.
Does not auto-generate multi-crop sets for Stories vs feed in one click.

Questions

Are these official platform dimensions?

They are UtilBloom presets based on commonly published sizes. Check Instagram, LinkedIn, YouTube, Meta, Discord, or WhatsApp help centres for the latest guidance before paid campaigns.

Can I enter custom width and height?

Yes. Presets fill the width and height fields; you can edit them before processing, or use Image Resizer for free-form work.

Is my image uploaded to UtilBloom?

No. Resize runs in your browser on the selected file.

Why does a platform still crop my image?

Apps often apply additional circular masks, UI overlays, or aspect crops. Leave safe margins around faces and logos.
