When it comes to sharing your photographs online, there are plenty of options available in the market. However, Flickr has been one of the most popular choices for several years now. But with Flickr phasing out their free plan in early 2019, many users may be looking for alternative platforms to showcase their photos. That being said, here are some of the best online photo-sharing sites that are free alternatives to Flickr.

1. Google Photos: Google Photos is one of the most popular and user-friendly photo-sharing platforms out there. It allows you to upload unlimited high-quality photos and videos for free. You can also create albums, share your photos, and even collaborate with other users. Additionally, Google Photos also uses AI to automatically create albums, collages, and animations for you.

2. Piwigo: Piwigo is an open-source photo-sharing platform that allows you to organize and share your photos and videos with complete control. The platform is available for free, but you will need to set up your server to use it. Piwigo also offers a range of plugins and extensions, allowing you to customize your photo-sharing experience as per your preference.

3. 500px: 500px is a community-based platform that allows photographers to showcase their work and connect with other photographers. Although the free plan limits the amount of uploads to seven photos per week, it is still an excellent platform to build your online portfolio and connect with other professionals.

4. Imgur: Imgur is primarily known as a platform for uploading memes and GIFS, but it’s also a great option for sharing your photos with others. It’s free and straightforward to use, but the platform is designed more for sharing individual images rather than creating a collection of albums.

5. SmugMug: SmugMug is a premium platform, but it offers a free plan that lets you upload up to 20 photos per week. The platform focuses heavily on customization, allowing users to create their websites with a personalized domain name. The platform is sleek and user-friendly, making it an excellent option for those looking to showcase their work online.

In conclusion, these are some of the best online photo-sharing platforms that are free alternatives to Flickr. Each platform has its unique features and advantages, so you can choose the one that best suits your photo-sharing needs. Whether you’re a professional photographer or just starting, these platforms offer you an opportunity to showcase your photography skills and connect with other photographers from around the world.
