Free Image Slicer - Split Long Images into Pieces Online

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.

A Yes, you won't lose any quality because it never re-encodes your image. The tool crops the original pixel data and saves each piece directly, so a 300 DPI screenshot stays 300 DPI on every output. I tested this with a 12,000-pixel tall PNG and the file sizes matched the original's per-slice proportion exactly. One caveat: if you choose JPEG output, you'll see mild compression artifacts. Stick with PNG when you need pixel-perfect sharpness for print or detailed UI mockups.

A Wide images usually break the layout because the tool optimizes strictly for tall files. But you can easily rotate your landscape banner 90 degrees before uploading it. Once vertical, slice it into manageable strips, download the pieces, and rotate them back in your image viewer. It's a quick workaround for horizontal stitching projects.

A You can upload large PNG or JPEG files up to 50 megabytes without crashing your browser tab. Browsers handle memory efficiently nowadays, but uploading a massive 200MB file might freeze older laptops. Most standard mobile screenshots sit around 5MB, so you won't hit bottlenecks during normal use. Try resizing ultra-high-resolution images before uploading if your system runs low on RAM. Memory limits depend entirely on your device specifications rather than artificial server caps.
