Social media image resizer
Resize a batch of images to the size each network asks for, or to any size you type. Choose crop, blur fill or a colour background, set a file size limit if you need one and download everything as a ZIP. The images never leave your browser.

Your images stay on this device. Nothing is uploaded: the work happens in your browser.
Fill one box to keep the proportions, or both for an exact frame.
The picture keeps its proportions. It is saved at the best quality that fits the limit, and made smaller in pixels only when quality alone is not enough.
Optional. In "Network size" and "Free size" the pixels stay exact and only the quality changes.

The images are ready. Where do they send people?
A post can carry one link, a profile only one too. Put your shop, booking, menu and contacts on a single VISU Link page and use that link everywhere. Free to start.
Create your VISU Link See VISU LinkHow to use it
- Drop your images in the box, choose them from your device or paste a screenshot. Up to 30 at a time.
- Pick "Network size" and choose the placement, or "Free size" and type the pixels. "Only make it lighter" keeps the size and reduces the weight.
- When the shape of the photo does not match, choose crop, blur fill or a colour. Add a limit in KB if the site you are sending to has one.
- Press the button, check the before and after sizes in the list and download one image or the ZIP with all of them.
Examples
Product photos for a portrait post
Drop ten photos, choose Instagram "Portrait post 4:5" and "Fit with blur": every photo comes out at 1080 × 1350 px with nothing cut off, in one ZIP.
YouTube thumbnail under 2 MB
Choose YouTube "Video thumbnail 16:9", JPG and a limit of 2000 KB. The picture stays at 3840 × 2160 px and the quality is adjusted to fit.
A logo on a wide cover
Choose a LinkedIn cover and "Fit with colour" with your brand colour: the whole logo stays visible instead of being cropped to a strip.
A form that rejects heavy files
Choose "Only make it lighter" and type 200 KB. You see the weight before and after for each image.
Questions
Are my images uploaded to a server?
No. The page loads once and then works alone: the browser opens the files, resizes them and builds the ZIP on your device. You can check it: after the page loads, turn off the internet and it still works, or look at the network tab of your browser while you resize.
Where do the sizes come from?
From each network's own help page, read on the date shown above the table on this page. Each row links to its source and says whether the page states that exact size or the size follows from the ratio it states. Sizes we could not confirm on an official page are left out.
Crop, blur or colour: which one should I use?
Crop fills the frame and cuts what is left over, which is best when the subject is in the middle. Blur and colour keep the whole picture and fill the empty space, which is safer for text, logos and screenshots.
How does the file size limit work?
The tool looks for the highest quality that stays under the limit. With a network size or a free size the pixels are never changed, so if the limit is impossible you are told and get the lightest version. In "Only make it lighter" the picture can also shrink in pixels.
JPG, PNG or WebP?
JPG for photos. PNG for logos, text and anything with transparency, at the cost of heavier files. WebP is lighter than JPG at the same look, but not every site accepts it. In JPG, transparent areas become white.
Will the network compress my image again?
Usually yes: networks re-encode what you send. Sending the size they ask for avoids a second resize on their side, which is where most blur comes from.
Does the result keep the photo data (EXIF)?
No. The new file has only the pixels: camera model, date and GPS position are not copied. Phone photos taken sideways come out upright.
Is there a limit of images or size?
Up to 30 images at a time and 40 MB each. iPhone HEIC photos need to be exported as JPG first, because most browsers cannot open them.
