In that case, result canvas can be with bad quality or just empty, or browser can fall with memory limit exception. ![]() This solution will be faster but will be the worse solution for high-resolution images, for example 6000圆000 pixels. You can use offscreen canvas, without attaching the canvas to a body, and resize an image.(good for High-resolution images, without canvas size restriction) You can get image data from a file by jpg-js (or draw an image on canvas)and then resize canvasImageData by resizing lib pica.You can convert js file to image bitmap by jpg-js.And you can resize only by this lib, but in a case of resizing from very large image to very small, quality will be very bad.Best way for high-res images is to convert file to bitmap by jpg-js and then resize this bitmap by Pica lib.These solutions good for resizing not just converting image to base64. It is straight forward to do: function imageToDataUri(img, width, height) // Use it like : var newDataURI = await resizedataURL('yourDataURIHere', 50, 50) įor more details you can check MDN Docs : This will provide a bitmap buffer and native compiled code to encode the image data. So I tried to the use the package react-image-file-resizer to resize dimensions & reduce size of images and the problem is when i want to get result as String to send it back to the component, I always get this Promise in the method imageFileResizeCompression below.įile : /** Convert an "Image URL" to a "Blob" type.Ĭonst convertImageURLToBlob = async (imageInputURL: string) => from '.A way to avoid the main HTML to be affected is to create an off-screen canvas that is kept out of the DOM-tree. ![]() I am using an API to get images that have high resolutions & sizes, but when loading the images in the component it took time to load and even the CPU & HDD are used with high percentage when scrolling the list.
