How do I resize an image to Facebook Cover (820×312)?

Upload your image, confirm the target dimensions, then download the resized result. If you are preparing for social media, resize first and compress after to keep file size small.

Should I resize or compress first?

Resize first to set the correct dimensions, then compress to reduce file size while keeping the final pixels unchanged.

How to Resize an Image Online (4 Steps)

Resizing images for the web and social media only takes a few seconds with fbutube. No desktop software, no signup, and no watermark.

Upload your image or images. Click the dashed upload area or drag & drop files directly onto it. You can upload a single JPG/PNG/GIF/WebP or choose multiple files for batch resize. The tool reads the original pixel dimensions automatically.
Set width × height (pixels) or pick a preset. Type any integer W and H, or click one of the preset chips below the header: 1200×630 (Open Graph / social link previews), 1080×1080 (Instagram square), YouTube Thumbnail (1280×720), Facebook Cover, Instagram Post, and 1080×1920 (Stories / Reels). Presets are one click.
Click Resize Image. Your file(s) are sent to the resizing endpoint and re-encoded at the exact dimensions you specified. Batch mode walks through each file one at a time and reports progress.
Download single or ZIP. For one image the download button appears next to a preview. For a batch, download each result individually or press Download ZIP to receive every resized file in one archive with clean filename suffixes (e.g. sunset-1920x1080.jpg).

Pro tip: resize first, then run the output through the Image Compressor to strip extra KB without changing the final pixel dimensions. This two-step workflow is the fastest way to nail every platform's upload guidelines for social posts, OG cards, and website banners.

Common Image Dimensions

Dimensions (W × H)	Aspect Ratio	Typical Use
1920 × 1080	16 : 9	Full HD desktop wallpaper, YouTube thumbnail upload source, 1080p video stills, HD blog hero images.
1280 × 720	16 : 9	YouTube thumbnails (official recommended size), HD embed previews, widescreen blog cards, email banners.
1080 × 1080	1 : 1 (square)	Instagram feed posts, LinkedIn image posts, Facebook carousels, product shots for ecommerce, square tweet images.
1080 × 1350	4 : 5 (portrait)	Instagram portrait posts (maximum in-feed vertical real estate without being cropped to square).
1200 × 630	~1.91 : 1 (OG)	Open Graph / Facebook / LinkedIn / Twitter (X) link preview — the single most important size for SEO and social share cards.
1080 × 1920	9 : 16 (vertical)	Instagram Stories, Reels, TikTok videos, YouTube Shorts, Snapchat-style vertical creative.
1280 × 720 (YT Thumbnail)	16 : 9	Uploaded custom YouTube video thumbnail — minimum allowed upload size is 640×360, but 1280×720 is the official spec.
2560 × 1440	16 : 9 (2K / QHD)	Ultra-crisp banners, Retina/HiDPI 2× assets for the 1280×720 slot, high-res social campaign art before compression.

When in doubt, start from the largest row in this table that matches your target platform and then compress the output afterwards. That way you have a single clean master asset you can down-sample for any smaller slot without re-editing the original source file in Photoshop or Canva.

Why Use This Image Resizer?

🎯 Exact Pixel W × H

Type any width and height and every output comes back at the exact integer dimensions you requested, no approximation, no auto-crop. Perfect for upload slots with strict pixel rules (OG tags, YouTube thumbnails, ad banners).

📐 Presets for YouTube / FB / IG

Memorizing platform specs is a waste of time. One click on 1200×630 (OG), 1080×1080, YouTube Thumbnail, Facebook Cover, or Instagram Post fills the inputs with the exact size every social network expects.

📦 Batch + ZIP Download

Drop a dozen product photos or blog graphics, set one target W×H, then download a single ZIP containing every resized file with clean filenames (image-1200x630.jpg). No downloading results one by one.

🔒 Simple & Safe

No account, no watermark, no mandatory newsletter popup. Upload, resize, and leave. Processed files are cleared automatically so your creative assets never linger on a public server waiting to be rediscovered.

Frequently Asked Questions

Can I make an image larger (upscale) without losing quality?+

This tool faithfully resizes pixels to whatever dimensions you type, but upscaling a small image (e.g. turning a 300×200 source into 1920×1080) will always look softer or blurrier than the original — there is no way to invent detail that was never captured. For best results, always start from the highest-resolution source you have. If your input is already high resolution and you are only sizing up modestly (e.g. 10–20%), the visual impact is usually minimal.

Does the tool lock aspect ratio automatically when I type width or height?+

Currently the two width/height inputs are independent, so you can freely stretch to any ratio or leave them matched. The preset chips (1200×630 OG, 1080×1080, YouTube Thumbnail, Facebook Cover, Instagram Post, 1080×1920) all come with correct platform ratios baked in. If you started from an uploaded image, the width and height are pre-populated with the original dimensions so you only change the values you want.

When should I use the preset chip links instead of typing custom pixels?+

Use the preset chips whenever you know the platform you are targeting — they save you from memorizing specs. Clicking 1200×630 (OG) pre-fills the exact size every social network expects for Open Graph link previews; YouTube Thumbnail sets 1280×720; Facebook Cover is 820×312; Instagram Post sizes to 1080×1080; and the 1080×1920 preset is for vertical Stories, Reels, and TikTok. The preset row appears right below the rating box.

Can I batch-resize multiple images to DIFFERENT sizes in one run?+

No — a single batch run uses whatever width and height are currently typed. If your uploads need five different final sizes, upload them in five separate groups (one size per group). Each run only takes a few seconds. An alternative workflow: upload the biggest size first, resize to your largest target, then take that output and run it again for the next smaller dimension. Cascading avoids repeatedly re-uploading originals.

What is the maximum file size or pixel count I can upload?+

Because resizing happens on our processing servers, there is a practical upload limit per file (typically 10–20 MB depending on format). Extremely large source images (e.g. 8000×8000 raw photos) may be rejected. If your file is too big, compress it first with the Image Compressor tool, then bring the compressed result back into the Resizer — this almost always works because the Resizer then only has to handle a smaller starting file.

Is PNG transparency (alpha channel) preserved after resize?+

Yes. PNGs with transparent backgrounds are re-encoded as PNG and the transparent pixels stay intact. The same applies if you are starting from a transparent WebP. JPG does not support transparency at all, so if your source is JPG, there is no alpha to lose — but converting a transparent PNG to JPG would fill transparency with a solid color. For resizing alone, format stays the same as the upload.

How is this different from resizing in PowerPoint, Paint, or WordPress?+

Dedicated image-resizing pipelines use better re-sampling filters than most office apps and CMS editors, which means edges stay sharper and fine detail (text, logos, hair) survives better at smaller sizes. Also, this tool handles all common formats through a single drag-and-drop form that gives you batch mode and ZIP download, which office editors and WordPress generally do not.

Does batch resize apply the same dimensions to every uploaded file?+

Yes. Whatever width and height values you have in the W × H inputs are applied to every image in the batch before each one is processed individually. If some images are portrait and some are landscape, they all become the exact W×H you typed. If preserving orientation is important, split your upload into portrait and landscape batches and set the matching W×H for each.

Can I resize an animated GIF and keep the animation?+

The current resizing endpoint re-encodes a single frame. For animated GIFs, the output will be a static JPG or PNG of the first frame rather than a looping animation. If you need to keep a GIF animated, reduce its pixel dimensions in a dedicated GIF editor first, then optionally run the single-frame output back through the resizer for a final platform-perfect size.
