How to resize for social media
- Drag your images onto the box above, or click to browse. Several at once is fine; all of them receive the same preset.
- Choose a Target size from the list, then choose Cover (fill the frame and crop the overflow) or Contain (fit the whole image and pad the rest). In Contain mode a colour picker appears for the padding.
- Pick a Format: JPG, PNG or WebP. The result shows the exact pixel size and file size.
- Click Download on any image, or Download all. Files are named with the preset first, such as ig-post-photo.jpg, so batches for different platforms don't get mixed up.

Platforms update their recommendations from time to time, so treat these as widely used sizes and check the guides below if a platform changes its layout. Profile pictures and channel banners are not included as presets.
Cover or Contain? A worked example
Take a 4000×3000 landscape photo and a 1080×1920 story. With Cover, the photo is scaled until it fills the height, to 2560×1920, and then only the centre 1080 pixels of width are kept. That is just 42% of the original width, so people at either side of the frame disappear. With Contain, the photo is scaled to 1080×810 and centred, leaving roughly 555 pixels of padding above and below in your chosen colour. Nothing is lost, but a lot of the frame is empty.
The rule of thumb: use Cover when the source already has a similar shape to the target, or the subject is centred. Use Contain for charts, screenshots, posters and group photos where every edge matters. Cover always crops around the centre, and there is no way to shift the crop. If your subject is off to one side, trim the photo first with the image cropper, then run it through this tool.
The padding colour fills the empty space in every format, including PNG, so there is no transparent option here. White suits clean product shots; picking a colour from the image itself, such as the sky or a studio backdrop, makes the padding look intentional.
Start from a large enough source
The tool also scales up when needed. A 640×480 image sent to a 1080×1080 post is enlarged by 2.25 times in Cover mode, which makes it visibly soft. For crisp results the source should be at least as large as the target on both sides, and in Cover mode larger still on the side that gets cropped.
Keep important content away from the edges
Apps overlay buttons, captions and profile information on top of images. Stories and Reels commonly lose roughly the top and bottom 250 pixels of a 1920-pixel frame to interface elements, so keep faces and text in the middle. Facebook covers and X headers are cropped differently on phones and desktops, so centre your key message there too. Thin text on a busy photo gets harder to read when a platform compresses it, so favour larger type and higher contrast.
Choosing the format
JPG is the best default for photos and is saved at a fixed 90% quality, giving a sharp image at a modest file size. PNG suits graphics with text, flat colour, or logos, but its files are larger. WebP gives small files, although not every platform accepts it as an upload. Note that most platforms compress uploads again on their side, so avoid heavily compressed sources: uploading an image that is already close to the final size keeps the extra loss small.
Limits of this tool
One preset applies to the whole batch, so a campaign for several platforms needs one pass per size. There is no manual position or zoom control. Presets are fixed in size rather than editable; for any other dimensions use the image resizer.
Is it private and safe?
Yes. Toolyard resizes images inside your browser on your own device. Your files are never uploaded anywhere, so they stay completely private.

Frequently asked questions
What size is an Instagram post?
A square Instagram post is 1080 by 1080 pixels. This tool also has presets for the 1080 by 1350 portrait post and the 1080 by 1920 Story or Reel. Portrait posts take up more space in the feed, which often helps them stand out.
Cover or Contain: which should I pick?
Cover fills the whole frame and crops the overflow around the centre, so it works best when the subject is centred or the image already has a similar shape. Contain shows the entire image and pads the rest with a colour you choose. Use Contain for screenshots, charts and group photos where nothing may be cut off.
Will my image be stretched?
No. Both modes keep the original proportions. Cover scales until the frame is full and trims the extra, and Contain scales until the whole image fits and fills the leftover space with a background colour.
Can I choose which part of the photo is kept in Cover mode?
No. Cover always crops around the centre. If your subject is off to one side, crop the photo first with the image cropper to put the subject near the middle, then resize it here.
Does Contain support a transparent background?
No. The padding is filled with the colour you pick in every format, including PNG, so the result is always a solid rectangle. If you need transparency, use the image resizer or the image cropper instead.
Can I resize several images at once?
Yes. Drop several images and they all get the same preset, fit mode and format. To produce sizes for multiple platforms, change the preset and download again; filenames start with the preset name, so versions stay separate.
Are my images uploaded?
No. Everything runs on your device and nothing is sent anywhere. Your files stay private.
Is it free?
Yes. It is completely free, with no watermarks and no sign-up.
