Free Image Slicer - Split Long Images into Pieces Online

A It's super fast. For a screenshot that's, say, 10,000 pixels tall, and you're splitting it into 5 pieces, you're looking at just a couple of seconds. The exact time depends a bit on your computer's specs and internet speed, but it's designed for near-instant results.

A This tool runs entirely in your browser, so the limit depends on your device's available memory. Most modern computers handle images up to 50MB or 20,000 pixels tall without issue. Larger files may cause the browser tab to crash. For extremely long images, try splitting them into smaller chunks first or reducing the file size by saving as JPEG at 80% quality.

A Vertical splitting matches how we scroll on phones and browsers. Long screenshots, chat transcripts, and web page captures all run top-to-bottom. Horizontal splitting would be for panoramas or wide banners, which is a different use case. This tool focuses on one thing well: breaking tall images into stackable pieces. If you need horizontal cuts, you'd crop the image first to rotate it 90 degrees, then slice it here.

A That's a browser rendering quirk, not a tool bug. Browsers add sub-pixel anti-aliasing at cut boundaries, creating 1-2 pixel gaps. Fix it by setting image-rendering: pixelated in your CSS or using object-fit: cover. Another workaround: slice images with a 1-pixel overlap. Set your cut height to 99px instead of 100px when you need 100px pieces. This compensates for those tiny gaps and keeps your layout seamless.

A No watermarks, no logos, no branding at all. Your sliced pieces come out exactly as clean as the original. I've seen too many free tools stamp their URL across your work, and we don't do that here. The output images are 100% yours, with zero alterations except the cuts you specified. Download them and use them anywhere.

A Yes, you will. The slicing process strips EXIF data because we're creating new image files from your original. GPS coordinates, camera settings, and creation timestamps won't carry over to the pieces. If you need that metadata preserved for photo forensics or archiving, this tool won't be the right choice. For social media posts or web graphics though, missing EXIF data usually doesn't matter at all.

A Yes, you get a live preview right after you upload your image. The tool shows dashed lines exactly where each slice will fall. You can tweak the slice height or count and see the preview update instantly. No guesswork needed — just adjust until you're happy, then hit download. This saves time if you're slicing a 15,000-pixel screenshot into specific sections for a tutorial.

A Simple. Upload your image, then select 'Count' mode and set the number of pieces to 4. The tool divides the total height by 4 automatically, handling uneven pixels by making top slices slightly larger. For a 1200px tall banner, each piece will be 300px. Works great for Instagram grids or 2x2 brochure panels. Download them all as a zip to keep things organized.

A Nope, no sign-up needed. This tool runs entirely in your browser, so you upload, slice, and download without ever sharing an email address. The whole process takes about 30 seconds from upload to zip download. Your files never touch a server, which means there's no login required and no storage limits. That's actually a major privacy win — photographers can split client galleries without worrying about third-party access. Just open the site, drop your file, and you're done.

A Nothing changes to your original. The tool reads your uploaded image and creates brand-new files for each slice, leaving the source untouched on your device. You can test this yourself: upload a screenshot, slice it into 3 pieces, then check the original's modification date — it won't budge. This makes it safe for editing client work or personal archives. One tip: because everything runs in your browser, closing the tab deletes all sliced pieces. Download your zip before navigating away.
