Local limits

Browser memory limits

Browser-local processing is private and fast, but it still runs inside your device memory and browser tab. Large files can exceed what the tab can safely decode, parse, rewrite, or download.

What to know

1

Large files can be valid and still fail locally

Huge images, ZIP archives, XLSX workbooks, PDFs, JSON payloads, and CSV files can exceed practical browser memory. A local failure is not always a format error.

2

Use inspection before conversion

Check file type, file size, dimensions, row count, archive entries, or PDF page count before trying to generate a new output from a large source.

3

Split or narrow the task

When possible, split the source, reduce image dimensions, remove unused sheets or rows, list archive contents before extraction, or choose a temporary server job if the tool supports one.

4

Keep the tab open

Browser-local tools depend on the active tab. Closing, reloading, or memory pressure from other tabs can interrupt work before you copy or download the result.
