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

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

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

Q: Are my images uploaded?

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.

Q: Which formats can I use?

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.

Q: Can I process a batch?

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

Q: Will a smaller file look the same?

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.

Q: Does this tool preserve animation from animated inputs?

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.

Q: Does a WebP quality setting of 100 guarantee lossless output?

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.

Check pixels, resolution and DPI. Resize, compress, convert and remove metadata — without uploading your images.

Output Format:

Each option is checked by requesting a Canvas export and verifying its MIME type. Unsupported choices are disabled. Auto keeps the input format when encodable; otherwise it uses PNG.

1 KB = 1,000 bytes. Leave blank to use quality only. Target mode searches quality first, then reduces pixels. PNG/GIF/BMP/ICO/SVG switch to WebP to preserve transparency; choose JPEG if your form requires it.

DPI metadata is not image quality. Changing a DPI tag does not add pixels or sharpness.

How these image tools work

Local image processing

Images are processed on your device, without server uploads. Moving between tools may temporarily store the original in this browser.

Runs in the browser

Canvas-based exports run one file at a time. Processing time depends on image size and your device.

Browser-supported formats

PNG and JPEG export are broadly available. WebP and AVIF need browser encoding support; GIF/BMP/ICO output is generally unavailable through Canvas.

Export pixel limits

Exports allow up to 16,384 pixels per side and 80 million pixels total. Available memory can impose lower limits.

Sequential batch queue

Add several images, process them in order, then download completed outputs individually or as a ZIP.

Encoding quality

Quality 100 does not guarantee lossless WebP. PNG encoding is lossless only for the rendered pixel buffer; browser decoding or color handling may change source pixels and metadata. Exports are still images.
