DPI metadata is not image quality. Changing 72 DPI to 300 DPI does not add pixels or sharpness.
Check, then fix — in three steps
Drop an image
Add a photo or screenshot. Pixels, DPI, size, format and metadata are read in this browser.
Read the report
See dimensions, megapixels, embedded DPI, print size, file size and whether EXIF or GPS exists.
Choose a fix
Resize, compress to a KB target, convert, check DPI, or remove metadata — still without uploading.
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.
All Image Conversion Tools
Explore all supported conversion routes. Everything happens locally in your browser.
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.
