SmillaEnlarger

I'm a photo editor (by profession). This is a fantastic app. I've compared with a few pro apps and this one is even better than some of the pro stuff. Keep it up. The price is 100% great for everyone!

Indispensable. The UI could use some streamlining but the results are phenomenal—could it really be this easy? Now I wish this was adapted for upscaling video.

Definitely works as described and others define values. Have used occasionally and confidently to improve work of others and myself, just a smidgen...

looks good, but no choice of algorithms. If the author could add a list of algorithms and upgrade to a paid version, I'd gladly pay.

2014- Quick and first glance seems really useful tool under OSX10.9 still...

Overall, the program works perfectly. Better yet, the program is free, customisable, and includes batch process. I don't have any professional applications to compare to, coming bicubic sampling. The speed is definitely slower than Bicubic, so it's not instantaneous, nothing to complain about really. I found that the interface does lag a bit when the program is batch processing at the time, and which causes me unable to move my mouse (I can move the mouse but it will cause incorrect settings chosen in the menu for example). I haven't seen any crashes yet.

A long time ago, I got a copy of Shortcut S-Spline on a MacWorld CD or something. It only ran under OS9, but was amazing because I could take the pictures that were taken with my elderly 1.3 megapixel camera, blow up their resolution and then print them out, and they would look amazing on paper. I've been looking for a replacement for that since updating to OSX. My camera is no longer 1.3mp, but I like to have the option of enlarging some images. S-Spline still exists in the form of PhotoZoom, but costs an exorbitant sum of money to buy, money which I just can't justify spending to increase the DPI of an image that I probably won't print anyway. Then someone mentioned SmillaEnlarger and I gave it a go, not expecting much. Lo and behold, it did an admirable job. It's not as perfect as PhotoZoom's algorithm, but for a few quick enlargements its more than adequate.

Great app... simple does what it is supposed to do. Make pictures bigger.

Just tried this for a quick enlargement of a photo from 640 × 458 to 1024 × 733 (minimum dimensions requested from the recipient) ... looks fantastic! Effortless and pretty intuitive, I got the job done in about a minute after downloading. Lots of configurable options in the preview before saving your expanded file. Great!!

This is a wonderful piece of software. Any new updates in the near future?
