Browser-only tools
The public PDF splitter, merger, organizer, images-to-PDF tool and image compression/conversion tools, including JPEG XL, process your chosen files in your browser. They do not upload those files to BigSplit. Outputs exist in the tab until you download them or leave the page. Your browser may retain downloaded files and normal website cache data.
Creative-worker tools
Background removal and image-to-3D send the selected image over HTTPS to BigSplit and its private processing worker after you confirm the processing notice. Images are normalized and metadata is removed before processing. The queue accepts requests while the worker is busy or offline, with a maximum wait of 12 hours before an unstarted request expires. Job status and completed results remain accessible for up to 24 hours after completion. Requesting a download link requires the browser session that created the job or a private result link sent by email. Download links last five minutes and can be used by anyone who has the link. Stored input and output objects each expire one day after their creation and are removed by storage cleanup. The PC worker deletes its local job files after processing and clears abandoned temporary job folders on startup.
Optional model notifications
When enabled, the model tool can send a one-time ready notification if you choose to enter an email address. The address is used only for that job, is kept private from the processing worker, and is deleted after successful delivery, after five unsuccessful delivery attempts, or when the request expires. Delivery attempts stop 24 hours after submission. Any unsent address expires with the temporary job record. Emails contain a private result link rather than an attachment. Anyone with that link can access the model while it remains available. Model notifications are currently disabled while the sender mailbox is being set up. Basic PDF and image tools do not ask for an email.
Accounts and server jobs
An account is optional for everyday tools. If you use an account, BigSplit stores your email address, sign-in token records and job history. Server PDF/audio jobs have retention limits shown on their results. Audible connections are encrypted and can be disconnected. Amazon sign-in is handled through Amazon, not a BigSplit password form.
Cookies and local storage
Account sessions use cookies. Creative jobs use a random, HTTP-only session cookie for access control and local storage to resume a saved job for up to 48 hours. The access cookie also lasts up to 48 hours. These identifiers do not contain your email. Rate limits use a salted hash of an IP address with short-lived counters. Do not share job download links with anyone you do not want to access the result.
Contact messages and service logs
The contact form stores your message and, only if you provide it, a reply email for up to 30 days. Standard server logs can contain IP addresses, request paths and operational details used to run and troubleshoot the site. Do not put passwords, payment details or sensitive file contents into the contact form.
Advertising
Advertising is currently disabled. If Google AdSense is enabled later, editorial pages may load Google advertising technology, subject to the applicable consent choices. Ad serving is gated by publisher configuration and consent-platform setup. Ads are excluded from file workspaces and result pages. This notice will be updated when advertising is activated.
Your choices
Use the browser-only tools when you want to avoid uploading a document. Save creative outputs promptly. You can clear site cookies to remove access to a creative session. For questions about data or an account, use the contact form and include enough information to identify the request without sending sensitive documents.
