No file-size limit — AI runs locally

Remove background from large files

Most background removers cap uploads at 5–12 MB. This one has no limit. The AI runs in your browser — your image is never uploaded, so there is no server-side cap. DSLR photos, 4K renders, 50 MB+ files — all processed at full resolution. Free, no signup.

How to remove the background from a large image file

Three steps. No file-size cap, no upload, full-resolution output.

  1. Drop your large image

    Drag a JPG, PNG, WebP, or HEIC file of any size into the tool, click to browse, or paste from your clipboard. There is no upload — the file stays on your device, so even 100 MB+ images load instantly.

  2. AI processes it locally — no size cap

    A segmentation neural network runs in your browser via WebAssembly and removes the background at full resolution. No server receives your file, so there is no 5 MB or 25 MB cap. The only limit is your device's available memory.

  3. Download the full-size transparent PNG

    Save the cutout as a lossless PNG at the exact same resolution as your input. A 6000×4000 DSLR shot stays 6000×4000. Use the before/after slider to inspect the result, and refine edges with the smart brush if needed.

Why other tools limit your file size

Server-based background removers upload your image, process it on remote hardware, and send it back. That round trip costs bandwidth and compute — so providers cap free uploads at 5–12 MB and paid plans at 25 MB. Anything larger gets rejected or silently downscaled before processing.

This tool takes a different approach. The neural network (U²-Net) runs locally in your browser via WebAssembly. Your file never leaves your device, so there is no upload bottleneck and no reason to restrict size. A 10 MB product shot and a 100 MB DSLR image go through the same pipeline — full resolution, no compression, no artificial cap.

When you need background removal without a size limit

  • DSLR and mirrorless camera photos — a single RAW-to-JPEG export from a 45 MP camera can be 20–40 MB. Most online tools reject it; this one processes it at full resolution.
  • 4K and 8K renders — CGI product renders and architectural visualizations are routinely 30–80 MB as uncompressed PNGs. No file-size cap means no pre-processing workaround.
  • Scanned artwork and documents — high-DPI scans (600+ DPI) for archival or print production create large files. The background can be removed without downscaling the scan.
  • Batch product photography — e-commerce studios shoot thousands of products. Combined with the bulk background remover, you can process up to 30 large files per batch without hitting a size wall.

For general-purpose background removal, the remove background from image page covers all formats. If quality preservation is your priority, see remove background without losing quality.

Frequently asked questions

What is the maximum file size I can process?
There is no fixed file-size limit. Because the AI runs locally in your browser via WebAssembly, your image is never uploaded to a server. The only practical constraint is your device's RAM. Modern laptops and phones handle 50–100 MB images without issue; high-end machines can go well beyond that.
Why do other tools have a file-size limit?
Server-based background removers must upload your file, process it on their hardware, and send it back. That costs bandwidth and compute time, so they cap free users at 5–12 MB and paid users at 25 MB. Since this tool runs the neural network in your browser, there is no server cost and therefore no reason to restrict file size.
Will a large image take longer to process?
Processing time scales with pixel count, not file size. A 30 MB JPEG and a 30 MB PNG with different resolutions will take different amounts of time. On a mid-range laptop, a 24-megapixel image typically finishes in 5–15 seconds. Faster GPUs and newer browsers speed this up further.
Does it work with RAW files from a DSLR or mirrorless camera?
The tool accepts JPG, PNG, WebP, and HEIC. If you shoot RAW (CR2, NEF, ARW), export as a full-resolution JPEG or PNG first — any photo editor or your camera's software can do this. The background removal will then process the full-size export without any file-size restriction.
Are my large files uploaded anywhere?
No. The neural network (U²-Net, about 4.5 MB) loads once and runs entirely in your browser. Your images never leave your device — nothing is uploaded, stored, or processed on any server. The tool works offline once the page has loaded.
Does the output quality drop for larger files?
No. The output PNG keeps the exact same pixel dimensions as your original. There is no downscaling, no resolution cap, and no JPEG re-encoding. A 50-megapixel input produces a 50-megapixel transparent PNG.
Can I process multiple large files at once?
Yes. Drop up to 15 large images at once and each will be processed at full resolution. For even higher volume, the bulk background remover handles up to 30 files per batch — still with no file-size limit.
What if my browser crashes with a very large file?
If your device runs out of memory, the browser tab may become unresponsive. Try closing other tabs to free RAM, or process the image on a desktop instead of a phone. You can also resize the image slightly before processing — going from 100 MP to 50 MP halves the memory requirement while keeping more than enough resolution for most uses.
Is this tool really free for large files too?
Yes. No signup, no watermark, no daily limit, no paid tier for larger files. The full-resolution output is always the default — there is no upsell. Since everything runs in your browser, there is no server cost to pass on to you.

Your files never leave your browser

The AI runs locally via WebAssembly — no upload, no server-side processing, no storage. This is exactly why there is no file-size limit: nothing needs to travel over the network. Once the page and the model have loaded, the tool works even offline. Read more on the about page.
