How to resize an image for social media

  1. 1

    Upload your image

    Start with the highest resolution source you have so the output stays crisp after resizing.

  2. 2

    Pick a social preset or enter custom dimensions

    Choose a ready template for Instagram, Facebook, TikTok, or other platforms. Need a non-standard size? Enter width and height in pixels or scale by percentage.

  3. 3

    Check the crop and safe zone

    Make sure faces, products, prices, and key text stay inside the visible area, especially for story templates with system UI at top and bottom.

  4. 4

    Download the final file

    Export the image ready to upload directly to the platform or your content scheduler.

Why social media image sizes matter more than you think

Resizing images for Instagram, Facebook, TikTok, and other platforms is not a cosmetic detail. A bad crop hides your price tag, cuts off a face, or removes the call-to-action button entirely. Every channel has aspect ratios audiences expect, and matching them makes your content feel native rather than rushed.

The golden rule: always start from a source image larger than your target size, then pick the right social media image size preset. Pay special attention to safe zones for text, especially in story formats where system UI overlays the top and bottom of the screen. After export, you can compress images online to reduce file size and speed up uploads without needing to re-crop.

If you repurpose content across multiple platforms, build a repeatable workflow: high-res master asset, then size variants, then compress and convert format, then schedule and publish. Adly's free tools handle these technical steps end to end. When you need to create ad designs, social posts, and videos from scratch with scheduling and direct publishing, try the full Adly platform at /ui.

One last tip: always preview on a mobile screen before final publish. Most of your audience, especially in MENA markets, scrolls social media on their phone first.

Image resizer FAQs

Is the image resizer completely free?

Yes. Use social presets, custom dimensions, and download your resized images without any subscription or forced signup.

What are the most common Instagram image sizes in 2026?

Square feed post at 1080x1080, vertical feed post at 1080x1350, and full-screen story or Reels at 1080x1920 are the most widely used. Use the presets and check platform updates periodically.

Does upscaling a small image improve its quality?

No. Enlarging a low-resolution image does not create real new detail and will look blurry. Always start from the sharpest source available and downscale to your target size.

What is the difference between resizing by pixels and by percentage?

Pixels let you set exact width and height values. Percentage scales the image proportionally, which is useful for quick proportional shrinks without calculating exact numbers.

Can I resize multiple images at once?

Depending on the tool interface, you may upload one or more files. For repeated batch work, standardize on one target size and repeat the process quickly.

How do I prevent logos and text from being cropped?

Keep important elements like logos, prices, and CTAs away from the edges of the image. Always review the preview after applying a story or cover preset.

Do I need to convert the image format after resizing?

Sometimes. Some platforms prefer JPG or WebP for faster loading. Use Adly's free image converter alongside this resizer tool.

Do I need an Adly account to use the resizer?

No. The resizer is free with no login required. An Adly account is useful if you want to create ad designs, schedule content, and manage your brands.

Does the tool support TikTok and Facebook sizes too?

Yes. The presets cover multiple social media platforms including Instagram, Facebook, TikTok, and more. Pick the closest template and fine-tune manually if needed.

Does switching presets change the aspect ratio?

Yes. Moving between a square template and a vertical one changes the aspect ratio. Review the composition after switching to make sure your product or subject is not cut off.

How do I prepare images for multi-placement ad campaigns?

Export a separate file for each common ad placement (feed, story, Reels). Keep the uncropped original as a master reference for any new sizes you need later.
