Frequently Asked Questions
- How do I crop an image to exact dimensions?
- Upload your image, enter the exact width and height you need in pixels (or pick a preset like 1080 x 1080), and click Crop. Convertify scales the image to fill that shape then center crops it to the precise size.
- Will cropping reduce my image quality?
- No. Cropping only discards the edges, so the area you keep retains its original quality. The scale to fill step uses a high quality filter, so the result stays sharp.
- Why is the crop always centered?
- Convertify uses center cropping, which keeps the middle of your image and trims equal amounts from the opposing edges. This is ideal for centered subjects and batch consistency. Manual crop positioning is on the roadmap. For now, if your subject is off center, a manual editor is a better fit.
- Can I crop to a specific aspect ratio?
- Yes. Pick a preset like 1:1, 4:5, 16:9, or 9:16, or enter exact width and height values that produce the ratio you need.
- Does cropping change the file format?
- No. A JPG stays a JPG, a PNG stays a PNG, and a WebP stays a WebP. To change format, use one of our conversion tools after cropping.
- What size should I crop for Instagram in 2026?
- For feed posts, 1080 x 1350 (4:5 portrait) is widely recommended because it fills more vertical space on a phone. The 1080 x 1080 square still works but is no longer the default. Stories and Reels are 1080 x 1920.
- What size is a YouTube thumbnail?
- 1280 x 720 pixels (16:9) remains the standard thumbnail size, saved as a JPG. Crop to 1280 x 720 and it will display crisply across devices.
- How do I crop a 2x2 passport photo?
- Crop to 600 x 600 pixels, which is 2x2 inches at 300 DPI. Note that passport photos also have head position rules that a center crop cannot enforce, so check the official requirements for your country.
- Can I crop several images to the same size at once?
- Yes. Upload multiple images, choose one target size, and crop them all to identical dimensions in one go. This is one of the things center crop does best.
- What is the difference between cropping and resizing?
- Cropping trims away the edges to change the shape and keep only part of the image. Resizing keeps the entire picture and only changes how many pixels wide it is. If you do not want to lose any part of the image, resize instead.
- Is it safe to upload my images?
- Yes. Files are processed on our server and automatically deleted within a few hours. They are never shared or used for any other purpose, and there is no signup required.
- What image formats can I crop?
- JPG, PNG, WebP, AVIF, GIF, and HEIC. Your image keeps its original format after cropping.
What cropping to exact dimensions does
Cropping changes both the shape and the size of your image by trimming away the edges until what remains matches the exact width and height you ask for. Convertify crops to the center: it first scales your image to fill the target shape, then trims equal amounts from the opposing edges so the middle of your photo stays in the middle of the result. Pick a preset like 1080 x 1080 for an Instagram square or 1280 x 720 for a YouTube thumbnail, or type any exact width and height yourself. Your image keeps its original format, so a JPG stays a JPG and a PNG stays a PNG.
Free online image cropper
Convertify is a free online image cropper that crops JPG, PNG, WebP, AVIF, GIF, and HEIC images to exact pixel dimensions in your browser. There is nothing to install, no account to create, and no watermark added to your result. Upload an image, choose a size, and download the cropped version in seconds. Because the image cropper runs on a fast Rust and libvips engine, even large photos are processed almost instantly.
Is this the right tool for you?
This cropper is built for one job done well: turning any image into exact pixel dimensions with the subject centered. It is ideal when you need a batch of photos all cut to the same size, a quick square for a profile picture, or a fixed ratio for a social post where your subject is already in the middle. It is not the right tool if your subject sits off to one side and you need to choose exactly what stays in frame, if you want a circular or shaped crop, or if you are trying to remove the background. For those, a manual editor is a better fit. If you only need to make an image smaller without cutting anything off, use resize image instead, which keeps the whole picture and just reduces its width.
How to crop an image to exact dimensions
Upload your image by dragging it in or clicking to select it. Choose a preset for a common size like Instagram, YouTube, or a profile avatar, or enter your own exact width and height in pixels. Click Crop, and Convertify scales the image to fill your target shape then center crops it to the precise dimensions. Download the result, or get a ZIP archive if you cropped several images at once. The whole process runs in seconds and never adds a watermark.
2026 social media and photo crop sizes
The most common reason people crop is to fit a platform's required dimensions, and those numbers change more often than most size guides admit. The table below lists current, verified 2026 dimensions for the platforms and uses our presets cover. Note one important 2026 shift: Instagram now widely recommends the 4:5 portrait format (1080 x 1350) in the feed, with the old 1:1 square (1080 x 1080) still supported but no longer the default. Last verified June 2026.

What is aspect ratio, and what does center crop keep?
Aspect ratio is the relationship between an image's width and its height, written as width:height. A 1080 x 1080 image is 1:1, and a 1080 x 1350 image is 4:5. Two images can share a ratio at very different pixel counts. When you center crop a typical 4032 x 3024 phone photo (a 4:3 shape) to a 1080 x 1080 square, the tool first scales it so the shorter side matches the target, making it 1440 x 1080, then trims 180 pixels from the left and 180 from the right to land at exactly 1080 x 1080. What remains is the central square of your photo. If your subject is in the middle, you keep it. If your subject is near an edge, it gets trimmed away, which is exactly when a manual editor serves you better than center crop. Unlike resizing, cropping permanently removes the trimmed pixels, so it is worth keeping your original file.
Common aspect ratios and what they are for
1:1 square is used for Instagram square posts, profile avatars, marketplace product photos, and passport pictures. 4:5 portrait is a widely recommended Instagram feed format because it fills more vertical space on a phone. 9:16 vertical covers Instagram Stories and Reels, TikTok, and YouTube Shorts. 16:9 widescreen is the YouTube thumbnail standard and common for in feed Twitter images. 4:3 matches older phone cameras and many tablet screens. 3:2 is the native ratio of most cameras and the standard for 4x6 inch prints. Knowing the ratio you need before cropping saves you from trimming the same photo twice.
Common crop examples
Some of the most common crops people need: to crop a photo to 1080 x 1080 for an Instagram square or a profile avatar, choose the 1:1 preset or enter 1080 by 1080. To crop an image to 1280 x 720 for a YouTube thumbnail, use the 16:9 preset. To crop a picture for an Instagram portrait post, use 1080 x 1350 (4:5). To crop a vertical image for a Story, a Reel, or TikTok, use 1080 x 1920 (9:16). To crop a product photo for a marketplace like Amazon or Etsy, use 1200 x 1200 (1:1). In every case the result is trimmed to the exact pixels you asked for, with the center of your image preserved.
Crop, resize, or compress: which do you need?
These three are easy to confuse but do different things. Cropping changes the shape and trims away the edges, which is what this page does. Resizing keeps the entire picture and only changes how many pixels wide it is, with nothing cut off: use resize image for that. Compression keeps both the dimensions and the whole picture but shrinks the file weight so it loads faster or fits an upload limit: try compress JPG or compress PNG. Many people who think they need to crop actually just need to resize or compress, so it is worth a moment to decide which one matches your goal. You can also change the file type afterwards with tools like PNG to WebP.
Quality, privacy, and limits
Cropping does not reduce the quality of the area you keep, because it only discards the edges. The scale to fill step uses libvips with a high quality filter, the same engine used in production image pipelines, so the result stays sharp at its new size. Your image keeps its original format, with no conversion unless you ask for one. Files are processed on our server and automatically deleted within a few hours, never shared or used for anything else. There is no signup, no watermark, and no limit on how many images you crop.
