Inside Fixora

Tool limitations

The honest boundaries of Fixora image, text, CSV, JSON and meeting workflows.

PDF documents

PDF inputs are limited to 20 MB each and 100 pages. Simple Word reconstruction supports single-column black text, basic headings/emphasis, flat lists and page sizes with inferred fonts and spacing. It refuses tables, columns, images, links, running headers/footers and unsupported text geometry. Explicit text extraction loses more structure; neither mode provides OCR. Static PDF merge refuses forms, annotations, signatures, attachments and actions. JPEG page export is a raster copy with white background and no annotations. Review downloaded files against the source.

Images

25 MB and 16 megapixels per file; batches: 20 files, 40 MB, 24 megapixels total. Output is capped at 16 megapixels. Target size is not guaranteed. Check the actual MIME and file size. JPEG uses your chosen opaque background; re-encoding can lose metadata, color profiles, animation or fidelity. SVG rejects external-resource references and strips active elements before decoding.

Text and lists

Copied-text and list workspaces accept 1 MB and 20,000 lines per input. Joining line breaks is not meaning-aware; review tables, poetry and hyphenated words. List comparison is exact membership, not fuzzy identity matching. Word counts and reading-time estimates are approximate.

CSV integrity and spreadsheet safety

CSV input is limited to 10 MB and 50,000 data rows with unique nonblank headers and rectangular records. CSV comparison requires unique nonblank keys and matches exact strings across the same named columns, regardless of order. CSV cannot force spreadsheet applications to retain leading zeros or prevent inferred dates. Cleanup formula protection is an explicit opt-in and changes exported text; comparison protection defaults on but can be turned off. Other CSV-producing helpers prefix formula-like cells with an apostrophe. This is not a guarantee against every spreadsheet formula risk.

JSON precision

Formatting preserves original number and string tokens, even duplicate property text; duplicate properties are warned about. Inputs are capped at 2 MB and 200 nesting levels; expanded formatting is capped at 8 MB. Structural conversion/diff rejects duplicate properties and numbers that cannot be represented without loss. No schema checking, JSONC or automatic repair. Nested object key order affects diff; missing/null cells can be indistinguishable in CSV.

Meeting time planning

Dates 1990-2100, 2-4 selected supported locations, duration 15-480 minutes. Source zone is explicit. Daylight-saving gaps and repeated hours are rejected, not guessed. Browser time-zone rules may be outdated; confirm important meetings. An ICS download does not check availability or send invitations.

Helpers and retired tools

Experimental helpers cover focused tasks with specific format and output limits. Review each result before relying on it. Opaque sRGB contrast is only a color-pair check, not accessibility certification. Former calculation/security/XML/CSS tools are retired and their bookmarks show notices.
