DPI metadata is not image quality. Changing 72 DPI to 300 DPI does not add pixels or sharpness.
How to Convert Images in 3 Easy Steps
01
Adjust Settings
Choose your target format and adjust the quality slider to find the perfect balance between size and clarity.
02
Upload Your Files
Select or drag and drop your images into the conversion zone. We support JPG, PNG, WebP, AVIF, and more.
03
Download & Save
Conversion happens instantly in your browser. Download individually or grab everything as a convenient ZIP file.
Why use this converter
Privacy First
Unlike other converters, we don't upload your files to our servers. All processing is done client-side.
Runs in the Browser
Each image is converted with the Canvas API on your device, one file at a time.
Modern Formats
Stay ahead of the curve with support for next-gen formats like WebP and AVIF for better web performance.
Pixel Safety Cap
There is no daily quota. Images wider or taller than 16,384 pixels, or over 80 million pixels, are skipped so the tab stays stable.
Batch Queue
Add several images, convert them in order, then download each file or a ZIP of the results.
Quality You Set
The slider affects JPEG, WebP, and AVIF. PNG output stays lossless. Animated files keep the first frame only.
Workflow Steps
1
Pick an output format. Use the quality slider, or type a target size in KB.
2
Drop one or more images. JPEG, WebP and AVIF search quality; PNG may switch to JPEG to hit a small cap.
3
Download each file or a ZIP of the batch.
Key Highlights
- Target file size in KB, not only a quality percentage.
- Quality slider still available when you want visual control.
- Local-first processing with no server upload.
- Batch compression and ZIP download.
- Works with JPG, PNG, WebP, AVIF, GIF, BMP, and ICO inputs.
- Need a fixed 200 KB cap? Use Compress Image to 200 KB.

Popular Format Comparisons
Evaluate compression ratio, quality behavior, and browser support before choosing a format.
WebP vs PNG: Which Format Should You Use?
WebP usually delivers smaller files, while PNG remains a strong choice for pixel-perfect assets. Use this comparison to choose the right format by scenario.
WebP vs JPEG: Performance and Quality Compared
JPEG is still the universal photo format, but WebP usually wins on bytes for the same perceived quality. Use this comparison to decide when to convert and when to keep JPEG.
WebP vs AVIF: The Next-Generation Format Battle
AVIF often compresses further than WebP, while WebP still wins on tooling and encode speed. Use this comparison when choosing a modern delivery format.
