PNG vs TSV
A detailed comparison of PNG Image and TSV (Tab-Separated Values) — file size, quality, compatibility, and which format to choose for your workflow.
PNG Image
Raster & Vector ImagesPNG is a lossless image format that supports transparency. It is ideal for graphics, logos, screenshots, and any image where preserving exact pixel data is important.
About PNG filesTSV (Tab-Separated Values)
Spreadsheets & DataTSV uses tabs instead of commas to separate values in tabular data. It avoids quoting issues common in CSV when data contains commas, making it popular for scientific and linguistic data.
About TSV filesStrengths Comparison
PNG Strengths
- Lossless compression — every save preserves the original pixels perfectly.
- Full 8-bit alpha channel for smooth transparency.
- Excellent for text, UI screenshots, logos, and line art.
- Royalty-free and an ISO standard (ISO/IEC 15948).
- Supports 16-bit color depth for high-fidelity work.
TSV Strengths
- No quoting needed — tabs in data are astronomically rare.
- Simpler parser than CSV.
- Preferred by databases, bioinformatics, and scientific pipelines.
- Opens cleanly in every spreadsheet app.
- Plain text, grep-friendly, diffable.
Limitations
PNG Limitations
- Much larger than JPEG for photographs (no perceptual compression).
- No native animation in most software (APNG support is inconsistent).
- No CMYK support — web and screen only, not print.
- Metadata capabilities are less rich than JPEG's EXIF.
TSV Limitations
- Tabs can be invisibly replaced with spaces by text editors.
- Carriage returns inside fields require escaping conventions.
- Less ubiquitous than CSV in business/consumer workflows.
- No metadata, no schema, no type information.

Frequently Asked Questions
PNG (Portable Network Graphics) is a lossless raster image format created in 1996 as a patent-free alternative to GIF. It supports transparency, making it ideal for logos, icons, and web graphics.
TSV (TSV (Tab-Separated Values)) is a spreadsheet format used to store tabular data in rows and columns, typically with multiple sheets per workbook, cell formatting, formulas, and optional charts. It is part of the spreadsheets & data family and is the native format of a specific spreadsheet application.
PNG files open natively in all modern operating systems, web browsers, and image editors including Photoshop, GIMP, Paint.NET, and Canva.
Excel, Google Sheets, LibreOffice Calc, and Apple Numbers handle most TSV files with high fidelity. For simple one-off viewing, Google Sheets and the Office web apps open TSV in the browser without installing anything. Convert to XLSX or CSV first if your target tool is strict about formats.
WebP offers 26% smaller file sizes than PNG with equivalent quality. Use WebP for web delivery when browser support is sufficient. Use PNG when maximum compatibility or professional editing workflows are needed.
Upload the TSV to KaijuConverter and pick XLSX, CSV, ODS, TSV, or PDF. Our LibreOffice-based pipeline reads the sheet data, preserves cell types (numbers, dates, strings), and writes a clean target file. Multi-sheet workbooks come back as a single multi-sheet export or a ZIP of per-sheet CSVs depending on target.
