图像滤镜
为本地JPEG／PNG／WebP组合调整亮度、对比度、饱和度、色相、灰度、棕褐、反色、模糊和透明度，并导出PNG／JPEG／WebP。
JPEG, PNG, or WebP only; up to 20 MB and 40 megapixels. SVG, GIF, HEIC, animated images, and camera metadata are not supported.
PNG retains alpha. JPEG fills transparent areas with white. WebP alpha support depends on the browser encoder.
Used for JPEG and WebP; PNG encoding ignores this setting.
LIVE PREVIEW
Choose an image to begin
Select a supported local image to preview its filters.
Output is limited to 10,000 pixels per side and 40 megapixels.
使用步骤
如何使用
- Choose a JPEG, PNG, or WebP image within the displayed file and pixel limits.
- Combine brightness, contrast, saturation, hue, grayscale, sepia, invert, blur, and opacity controls while reviewing the preview.
- Choose PNG, JPEG, or WebP output, set quality for JPEG or WebP, then download the filtered image.
A small, composable filter set
The controls create one standard Canvas filter string in this order: brightness, contrast, saturation, hue rotation, grayscale, sepia, invert, blur, and opacity. Every setting is explicit and can be combined with the others. This is a practical browser editor, not a raw-photo workflow: it has no crop, selective mask, layer, histogram, batch, or metadata editor.
Input, pixel, and output boundaries
The page accepts a single local JPEG, PNG, or WebP file up to 20 MB. The browser-decoded image must be no more than 10,000 pixels on either side and 40 megapixels; export keeps those decoded dimensions. PNG ignores the quality control, while JPEG and WebP use its 10–100% setting. JPEG cannot retain transparency, so transparent pixels are filled white for JPEG output. Canvas output does not retain EXIF, camera metadata, animation, or embedded file structure.
Local processing with browser rendering limits
The file is decoded, previewed, filtered, and encoded in your browser. Nothing is uploaded by this tool. Canvas filters and image encoders are broadly available in current browsers, but exact pixels, color-profile handling, WebP alpha handling, blur edges, and encoded size can differ by browser and device. Check the exported file in the intended destination when exact color or compression behavior matters.
常见问题
你可能还想知道
Which filters can I combine?
You can combine brightness, contrast, saturation, hue rotation, grayscale, sepia, invert, blur, and opacity. The page applies them in the order displayed in its details, so a different sequence in another editor can look different.
Why is quality unavailable for PNG?
The browser PNG encoder is lossless and does not use the lossy quality parameter. Quality affects JPEG and WebP output only.
Will this preserve image metadata or an animation?
No. The browser draws one decoded image frame into Canvas and creates a new file. Camera metadata, EXIF orientation records, animation, and other source-file metadata are not preserved.
Does the page upload my image?
No. Image selection, filtering, previewing, and download are handled locally in the browser.
