Why resize your images before posting them?
Every social network displays images at its own dimensions. If your photo doesn't match them, the platform crops or compresses it its own way.
For product photos, use «fit with background»: it shows the whole image without cutting off a corner of what you sell. Shrinking an image barely affects its quality; enlarging it does.
With the right size, your brand looks professional on every network.
Most common sizes
Instagram 1080 × 1080 or 1080 × 1350; stories and reels 1080 × 1920; Facebook 1200 × 630; YouTube 1280 × 720; online store, square at 1000 × 1000.
Which format?
JPG for photos (quality between 80 and 90 %), PNG for logos and transparency, and WebP for your website or online store.
Tiendana Enseña tip
Product photos that sell: light, background and consistency
You don't need a professional camera: a recent phone, light from a window and a plain background make the difference. Shoot during the day, without flash, with the product centered and filling a good part of the frame. Take one full shot and a close-up of the detail the customer wants to see: the texture, the label or the size.
Use the same aspect ratio and the same background across your whole catalog. A store where every photo is square with a white background looks tidy and trustworthy, and helps customers compare products without distractions. The first photo is the one that wins the click: use the one that best shows the whole product.
Did you know?
Facebook recommends uploading a page cover as a JPG of 851 × 315 pixels and under 100 KB so it loads faster. Here you see the file size before you download it.

Frequently asked questions
Are my images uploaded to a server?
No. The image is processed inside your browser and never leaves your device. That's why it's fast and private, and you can use it with photos of products you haven't launched yet.
What size should an Instagram post be?
1080 × 1350 pixels for portrait (4:5 ratio), which takes up the most space in the feed, or 1080 × 1080 for square. Stories and reels are 1080 × 1920.
What size is a Facebook page cover?
851 × 315 pixels, as a JPG and under 100 KB, as Facebook recommends. On phones it gets cropped at the sides, so keep your text and logo in the center.
What size should a YouTube video thumbnail be?
1280 × 720 pixels is the standard size, in a 16:9 ratio. YouTube requires a minimum width of 640 pixels and accepts larger images, always in 16:9.
What size should product photos be in an online store?
Square, at least 1000 × 1000 pixels, all with the same aspect ratio and the same background. That way your catalog looks tidy and customers can zoom in to see the details.
What's the difference between cropping and fitting with a background?
Cropping fills the whole space and trims whatever spills over the edges. Fitting with a background shows the whole image and fills the empty space with the color you choose, ideal for product photos.
Which format is best for me: JPG, PNG or WebP?
JPG for photos, PNG for logos, text or images with transparency, and WebP when you want the smallest possible file for a website. Social networks handle JPG and PNG well.
Do images lose quality when you resize them?
When you shrink them, hardly any: at a quality between 80 and 90 % a JPG looks the same and weighs much less. When you enlarge them, you'll notice, because the image has no more detail to show; that's why the tool warns you.
Why do my phone photos sometimes come out rotated?
Because your phone stores the orientation as separate data inside the file (EXIF). This tool reads that data and straightens the photo before resizing it, so you see it just like in your gallery.
Can I resize HEIC photos from my iPhone?
From the iPhone, yes: when you pick the photo from the browser, the phone hands it over as a JPG. On a computer it depends on the browser; if it won't open, export it as a JPG from the Photos app first.
