Instasize expands mobile photo‑video editing tools as vertical video apps gain popularity

Instasize, launched in 2012 as a solution for Instagram photo resizing, now serves over two million users with a suite of mobile editing features. The app offers more than 130 filters, collage creation, image resizing, and a premium tier that adds over 80 borders and advanced correction tools. Its creators promote it as a fast way to adapt visuals for social platforms without complex software.

At the same time, vertical video formats such as 9:16 have become standard on TikTok, Instagram Reels and Shorts, driving demand for mobile editing apps. Popular tools include CapCut, which uses AI for background removal and automatic subtitles; InShot for basic trimming and filters; KineMaster and Adobe Premiere Rush for layered editing; and free options like VivaVideo, YouCut, Google Photos and Magisto. These applications help creators produce professional‑looking vertical content quickly, boosting audience engagement on social media.
