Free Image Tools for Pixels, Resolution, DPI, Size & Format

Yes. No account or daily quota is required. Per-image pixel limits and device memory still apply.

No. Image processing stays on your device. Continuing from a report may temporarily store the image in this browser until the next tool reads it.

Inputs must be readable by your browser. PNG and JPEG export are broadly available; WebP and AVIF export depend on the browser. GIF/BMP/ICO output is not generally available through Canvas. SVG output embeds a bitmap, not vector paths.

Exports are limited to 16,384 pixels per side and 80 million pixels in total. Available device memory can impose lower limits.

Yes. Images are processed one at a time. Export tools offer individual downloads and ZIP downloads of completed outputs.

Not always. Lossy encoding and resizing can remove detail. Download the output and compare it at its intended display size. Smaller files do not guarantee ranking gains.

Animated inputs are exported as a single still frame; animation is not preserved. Original EXIF and other source metadata are not copied. Use the metadata tool for a report and an export recheck.

No. This tool passes a quality value to the browser’s WebP encoder; the tool has no separate lossless control, and 100 does not guarantee lossless output. PNG encoding preserves only the pixel buffer Canvas supplies: browser decoding or color conversion can change source pixels, and source profiles or metadata may differ. Keep the original when exact source data matters.
