Sometimes we have photographs that are too large to upload to a website or send by email, and other times, the opposite occurs. Resizing a small photo that a friend has given us or that we have rescued from an old device can end in catastrophe. Luckily, there are a number of online applications that you can run from any browser with which you can say goodbye to pixels and help you preserve your memories in high-resolution images.

This website allows you to excellently improve photographs of up to 3000 pixels and 10 Mb in size. Images processed by Bigjpg will not lose any detail in terms of their lines and edges, their focus or their colors when you enlarge them. This is an ideal application for illustrators and professional photographers, as it allows you to upload already large images. On the other hand, Bigjpg forces you to register to enjoy its functions without limits and offers advantages to paid users, who can upload photos of up to 50Mb

Among the possibilities that ImageEnlarger includes is that of uploading .gif or .bmp images, larger than traditional formats, up to 4,000 pixels. In addition, the user can select the desired height and width, although the resulting image will never exceed 4,500 pixels.

Image Upscaler is a complete online service with which, in addition to removing the background, generating illustrations or blurring an image, you can also enlarge your photos. This application incorporates artificial intelligence in its functions to increase the size of your images by up to 4 times quickly and easily.

The user can upload images in .jpg, .jpeg or .png formats up to 1000 pixels and 5Mb in weight. Despite these limitations —that, if necessary, you could convert the format or take only the part of the photograph that interests you—, Image UpScaler provides very good results, since it doesn’t diminish the quality of your digital images after processing them.

Belonging to the praised franchise of I Love PDF, I Love IMG has among its multiple functionalities that of resizing and enlarging images. However, the number of photos you can process at one time is limited. In principle, you will only be able to increase the resolution of .jpg and .png, although thanks to the converters that are included on this website, this will not impede you at all.

PicResize is, without a doubt, the most complete website in this selection. In addition to cropping, rotating or formatting images, this tool allows you to resize up to 100 images at a time and download them in a zipped folder. The user can choose whether to enlarge their photos by percentage or by setting a delimited width and height. This application stands out for its simple and intuitive operation, and best of all, it is totally free.
