Prepare a Facebook cover or post image with a centered crop, editable dimensions, and a preview that stays on your device.
IMAGE PLANNING
Choose the placement before you crop
A Page cover introduces the business or creator at the top of a public destination. A post image supports one update in the feed. Start with the placement, then choose a preset or enter the width and height you need for that design.
The preset names on this tool are starting points, not a promise that Facebook will display every pixel identically on every device. The width and height fields are editable because layouts and crops can change. After export, preview the result in the actual Facebook placement before publishing.
COMPOSITION
Crop without stretching important details
The resizer uses a centered crop to fill the selected canvas. Cropping removes content near the edges when the source and destination shapes differ; it does not need to squeeze faces or logos to fit. Choose a source image with enough room around the main subject.
Keep important text and faces away from the extreme edges, especially for a cover that may be shown differently on a phone and a desktop. If the preview cuts off a key element, choose another source image or adjust the composition before downloading.
FINAL CHECK
Review the export in the Page or post
The tool exports a PNG file. Your uploaded source stays in the browser during editing and is not sent to HitsBoost. Download the result, place it in Facebook, and review how the image appears on the devices your audience uses.
If the image introduces a Page, pair it with an accurate description and recent posts. If it supports one post, write a caption that explains the subject. Image preparation is one part of making the destination useful after someone opens it.
A CLOSER LOOK
A simple image checklist before publishing
Look at the resized image at its actual display size, not only enlarged in the editor. Small text that seems readable on a laptop may be difficult to read in a mobile feed. Keep the main subject visible, preserve contrast, and avoid placing a logo or essential message at the edge of a cover. If an image contains a claim or offer, confirm that the wording is current.
The exported PNG is intended for your Facebook upload. When you add images to a website, use a descriptive file name and an alt description that explains the image in its page context. Those choices help people using assistive technology and give search engines clearer information about the asset. They are separate from the dimensions you choose for a Facebook placement.
PRACTICAL CHECKLIST
Three checks before your next step.
Protect the subject
Leave space around faces, logos, and text so changing crops do not cut them off.
Preview after upload
Facebook can display the same image differently across placements and screens.
FREQUENT QUESTIONS
Questions about this tool
Does HitsBoost receive my image? +
No. The image is read and resized in your browser; this tool does not upload it.
Can I change the dimensions? +
Yes. The width and height fields are editable.
Will one cover look identical on desktop and mobile? +
No. Facebook may crop the same cover differently on each screen. Preview it on both after uploading.
Can I export WebP from this tool? +
The current browser tool downloads PNG. The images used on the HitsBoost site itself are optimized WebP assets.
Does the tool change my original file? +
No. It reads your selected image in the browser and exports a separate cropped PNG.
Why does the crop remove part of my image? +
The source and target aspect ratios differ. A centered crop fills the target without stretching the source.
Can I resize a Story image? +
Use custom dimensions and review the result in Facebook's Story editor before publishing.
