Privacy and Scope of Use
Sprite sheets and portable projects
Sprite Sheet Player and Sprite Sheet Studio process local static PNG/JPG/BMP images. A workspace is limited to 100 images / 100 MiB and 32 million source pixels; sprite sheet output is limited to 24 million pixels. Projects contain unencrypted source images and settings. Version 1 ZIP projects accept only uncompressed entries, up to 101 entries / 101 MiB and 100 MiB expanded data. Unsafe paths, duplicate entries, and corrupt files are rejected without replacing existing work. Batch ZIPs contain only successful results. Save projects you need; the site does not retain their contents permanently.
Your files stay in your browser
All tools are currently handled by the device. The file content, file name, and posted text will not be sent to the server. It does not use AI cloud processing, analytical tracking, or cookies, nor will it permanently store your files and text. Switching tools, refreshing and leaving the page will clear the files and results on this page, please export them first.
Local processing and public asset downloads
Opening the site still requires downloading its public application code. The first background-removal run downloads about 54.40 MiB of model and runtime assets from this site after you start processing. Progress appears in the tool. Your browser may cache public assets; Clear model cache removes the dedicated model cache. Fully offline use is not guaranteed.
Keep the original file and export a new copy
Tools do not overwrite original files on disk. Re-encoded images do not retain source metadata. Redaction does not automatically detect personal information, and background removal may miss details. Review previews, full exported images, and playback before using the results.
Image and audio restrictions
Static JPG/PNG/WebP maximum 20 MiB, 24 million pixels each. Each batch of images can be converted to a maximum of 10 images; a maximum of 10 images/100 MiB can be stitched, and the output is 24 million pixels; a maximum of 20 images/100 MiB of image list can be produced; a maximum of 6×6 images can be cut, and the ZIP can be 100 MiB. Audio tools are limited to 20 MiB, 120 seconds of mono/stereo PCM or float32 WAV, 8–96 kHz, and export PCM16 WAV.
File, text and data restrictions
Up to 50 files/100 MiB for renaming, packaging and SHA-256; 100 MiB each for two-file comparison; 20 files/20 MiB each for text transcoding and merging. Markdown 100,000 UTF-16 code elements/3,000 lines; JSON 2 MiB/100 layers; text statistics and URL original text 1 MiB each. CSV/TSV maximum 2 MiB/10,000 columns/200 columns; Base64 file or restoration result 5 MiB, original text including blank 8 Mi characters; UUIDs are limited to 1,000 per batch. Each tool also has a format check, and if it exceeds the limit, it will be explicitly rejected.
Check codes, encoding and content retention
SHA-256 does not verify origin, signatures, or viruses. Base64 is not encryption, the URL tool will not open the input URL; UUID is not a password. The text in the table is retained and the formula style is not modified. Other spreadsheet software may still interpret it on its own. JSON retains the original text of numbers, key order, and duplicate keys; text merging retains BOM and existing line breaks. The clipboard may be adjusted for line wrapping. Please export a new file if precise characters are required.
Color picking and watermarking
Color selection is based on sRGB pixels decoded by the browser and transparency is retained. Printing or installation color correction certification is not provided. A watermark is written to new image pixels but is not a copyright certification or a guarantee against removal.
Videos are processed locally
It only reads MP4/WebM imported from the device, and does not provide platform URL fetching or back-end video services. 100 MiB per file; capture, overview, and information tools support up to 300 seconds/UHD 4K. Information list can be up to 10 files / 300 MiB, no codec or source fps are speculated. Cropping and sound removal limit output to 1080p, up to 120 seconds, re-encoded to WebM on the fly, not lossless or frame-by-frame accurate; pagination will stop when entering the background.
Separate Video & Audio
Audio and video separation limited to 0.25–120 seconds/100 MiB/1080p, single enabled audio track, producing silent WebM/VP8 video and independent WebM/Opus audio. Maximum video size is 80 MiB, audio size is 16 MiB, total size is 100 MiB. Results will be provided only if both are successful. Not MP3/WAV or lossless extraction; no enabled tracks or multiple enabled tracks will be rejected, fully silent legal tracks will still be processed.
