A designer’s daily workflow is full of file format conversions: export WebP for front-end devs, convert to PDF for client reviews, create ICO for favicons, and TIFF for print.

If each format needs a different tool, you’ll end up with Photoshop, Format Factory, online converters, ffmpeg — five or more pieces of software. The switching cost is high, and each tool has different logic, making mistakes easy.

TinyOpt supports 9 input formats and 7 output formats — covering 90% of a designer’s daily format conversion needs in one tool.

9 Input × 9 Output Matrix

Input Formats	Output Formats
JPG, PNG, WebP, AVIF, BMP, GIF, TIFF	JPEG, PNG, WebP, GIF, TIFF, BMP, AVIF, ICO, PDF

Special note: ICO and PDF are output-only formats (BMP can be input and auto-converted to PNG).

01. One-Click Favicon (ICO) — Essential for Front-End Designers

Every website needs a favicon — the small icon in browser tabs — and it must be in ICO format.

Traditional workflow:

Design the icon in PS/AI
Export as PNG or SVG
Open an online converter, upload
Download the ICO
Possibly manually crop to 16×16, 32×32, and 48×48

TinyOpt’s approach:

Drag in your PNG icon file
Set output format to ICO
Automatically generates a 256×256 RGBA ICO (compatible with all sizes)

Even better: you can resize and convert in one step. If your source icon is 512px, set scaling to 256px and output as ICO simultaneously.

02. Client-Ready PDF — No Need to Open AI or PS

PDF is the most universal format for client reviews. But if your source files are PNG or JPEG screenshots, exporting to PDF usually requires opening Photoshop or Illustrator.

TinyOpt outputs PDF directly during compression: 150 DPI, RGB color, standard PDF format. Drag in multiple images, select PDF as output, and get a multi-page PDF.

Perfect for:

Website design screenshots → single PDF for client review
Multiple banner proposals → one PDF for side-by-side comparison
E-commerce product catalogs → multi-page PDF for suppliers

03. Format Conversion + Compression: Why Do It in One Tool

Most tools follow this workflow: edit/convert in one software → switch to another for compression → check results.

But every encode/decode cycle is lossy. TinyOpt’s approach is to convert and compress in one pass: read the original → encode directly to the target format with compression. One less codec cycle means better quality retention.

Extreme example: a JPEG original → convert to PNG → then compress. Mixing lossy and lossless operations can cause artifacts or bloated files. But going from JPEG straight to WebP with compression is the shortest path with optimal results.

04. 9 Formats — When to Use Which

Output Format	Best For	Typical Use
WebP	Web front-end	Website images, mobile H5
AVIF	High-performance front-end	Hero banners, image-heavy sites
JPEG	Compatibility	Email, WeChat, legacy apps
PNG	Transparency/pixel-perfect	UI assets, screenshots, logos
ICO	Icons	Favicon, Windows desktop icons
PDF	Delivery/preview	Client review, print proofs
TIFF	Print/archive	High-quality printing, archiving
GIF	Animation	Simple animations (complex ones use WebP)
BMP	Compatibility	Not recommended for web use

It’s Not Just About Formats — It’s About Efficiency

A designer’s work is fragmented across too many tools. Format conversion is just one piece, but it’s the most easily fragmented.

A typical front-end delivery flow:

AI/PS export PNG → online tool for ICO → another tool for WebP →
open compression tool → manually rename in file manager

The integrated flow:

AI/PS export PNG → drag into TinyOpt →
ICO output + WebP output + compression + rename — all at once

What you save isn’t technical time — it’s the cognitive cost of switching tools.

FAQ

01. Can it only output ICO at 256×256?

TinyOpt outputs ICO in 256×256 RGBA. Browsers automatically scale favicons to the needed size (16×16, 32×32, etc.). A 256px ICO covers all scenarios. If you need a specific size, use the resize feature to set the target width.

02. Can PDF output settings like margins and layout?

TinyOpt’s PDF output is image-only PDF, no text editing features. Images fill the entire page (150 DPI, RGB). For advanced layout, export as PNG and use AI/InDesign.

03. Will color space (CMYK/RGB) be lost?

TinyOpt’s conversion engine works in RGB color space. If your images are CMYK for print, verify color requirements before conversion. JPEG and WebP don’t natively support CMYK.

04. Can I batch-convert a folder to multiple formats at once?

One task outputs one format. If you need both WebP and AVIF versions of the same batch, run two separate tasks. Note that each run reads the original files, so keep your originals.

05. Should I keep BMP format?

For web and digital products, avoid BMP. BMP is uncompressed — typically 10× larger than JPEG. TinyOpt supports BMP output mainly for legacy system compatibility. Prefer WebP or JPEG for daily work.

Summary

A designer’s value lies in creativity and aesthetics — not mechanical format conversions. Consolidating 9 formats into one tool isn’t about showing off; it’s about installing fewer apps, memorizing fewer shortcuts, and focusing more on design.

Download TinyOpt Compressor and try dragging a design file in to see if PNG → ICO + WebP can be done in one pass.
