Bulk WebP Conversion for Designers: Figma, Sketch, Canva, and Adobe

Designers increasingly receive WebP assets from developers, download WebP images from the web for mood boards, or need to work with client assets delivered in WebP format. The challenge: most design tools — Figma, Sketch, older versions of Illustrator, and even Canva — do not support WebP natively. This guide covers the conversion workflow for each tool, plus bulk conversion for large asset sets.

Design Tool WebP Support Summary

Figma: Convert WebP to PNG Before Importing

Figma accepts PNG, JPG, SVG, GIF, and TIFF imports but not WebP. The drag-and-drop import or the "Place image" function will fail silently or throw an error for WebP files.

Sketch: Same as Figma

Sketch (macOS) does not import WebP. Convert to PNG first. The workflow is identical to Figma: convert, then drag into the canvas.

One advantage for Sketch users: since Sketch is Mac-only, the built-in sips command is available for fast batch conversion without installing anything:

# macOS batch convert all WebP to PNG for Sketch
mkdir -p ./converted
for f in *.webp; do
 sips -s format png "$f" --out "./converted/${f%.webp}.png"
done

Bulk Conversion for Large Asset Sets

When a developer hands off a design system or a client delivers a batch of brand assets in WebP, you need a reliable bulk conversion pipeline.

# Convert all WebP to PNG in current folder, save to ./converted
mkdir converted
magick mogrify -format png -path ./converted *.webp

# Convert all WebP to PNG recursively (subdirectories too)
find . -name "*.webp" -exec magick {} {}.png \;

# Convert to JPG with quality setting (for photographic assets)
magick mogrify -format jpg -quality 95 -path ./converted *.webp

from PIL import Image
import os
import glob

input_dir = "./assets/webp"
output_dir = "./assets/png"
os.makedirs(output_dir, exist_ok=True)

for filepath in glob.glob(os.path.join(input_dir, "*.webp")):
 filename = os.path.basename(filepath)
 stem = os.path.splitext(filename)[0]

 img = Image.open(filepath)
 out_path = os.path.join(output_dir, f"{stem}.png")
 img.save(out_path, "PNG")
 print(f"Converted: {filename}")

print(f"Done. {len(glob.glob(input_dir + '/*.webp'))} files converted.")

Canva: Use PNG for Logos and Icons

Canva's web interface sometimes accepts WebP uploads, but results are inconsistent. For professional design work, always upload PNG or JPG:

• Logos and brand marks with transparency: Convert to PNG before uploading — Canva preserves PNG transparency, letting you place the logo over any background color
• Product photographs: Convert to JPG at high quality (90%+) for reliable uploads
• Screenshot or UI images: PNG for sharpness (especially images with text)

Automating Conversion in a Design Workflow

If you regularly receive WebP assets from developers or clients, set up a one-command workflow that handles the entire conversion at the start of each project:

#!/bin/bash
# convert-assets.sh
# Usage: ./convert-assets.sh ./path/to/webp/folder

INPUT_DIR="${1:-.}"
OUTPUT_DIR="${INPUT_DIR}/converted-png"

mkdir -p "$OUTPUT_DIR"

webp_count=$(find "$INPUT_DIR" -maxdepth 1 -name "*.webp" | wc -l | tr -d ' ')

if [ "$webp_count" -eq 0 ]; then
 echo "No WebP files found in $INPUT_DIR"
 exit 0
fi

echo "Converting $webp_count WebP files to PNG..."
magick mogrify -format png -path "$OUTPUT_DIR" "$INPUT_DIR"/*.webp
echo "Done. PNGs saved to: $OUTPUT_DIR"

When to Convert to JPG vs PNG for Design

The choice between JPG and PNG for design tool imports depends on the image content:

Frequently Asked Questions

Can Figma import WebP files?

No, Figma does not support WebP imports. Convert WebP to PNG before importing into Figma. PNG preserves transparency and is lossless, making it the best format for UI assets, icons, and logos.

Does Sketch support WebP images?

No, Sketch does not support WebP import. Convert to PNG first. On Mac, use the built-in sips command for batch conversion without installing anything extra.

Can Canva accept WebP image uploads?

Sometimes, but inconsistently. For reliable Canva uploads, convert WebP to PNG (for logos and transparent graphics) or JPG (for photographs). PNG is especially important for logos where transparent backgrounds need to be preserved.

What is the best format to convert WebP to for design tools?

PNG is the best choice: lossless quality, transparency support, and universal compatibility with every design application. Use JPG only for photographs where smaller file size matters and no transparency is needed.

How do I batch convert a client's WebP assets to PNG for design use?

ImageMagick: magick mogrify -format png -path ./converted *.webp converts all WebP files in the current folder to PNG and saves them to a "converted" subfolder. All transparency is preserved automatically.
