Okay, I will bite...
The danger with these questions is always that each answer will generally be directed by that respondent's personal preference and familiarity of software that they happen to use within the context of their work requirements.
My experience: I use most Adobe apps since Photoshop 3.5. Extensive experience in just about any design app, from 2D to 3D, UX prototyping, and film & FX editing. But I also teach this stuff to either beginners and experienced people alike. I like to work in open source software (if possible) as well. I used or tried almost every design app ever published, from C64 times onward to today.
To me software is merely a tool that is used in a particular context. If it saves me time, makes me more efficient and it is fun to use: I will use it. I do not care about free or commercial. I do, however, tend to avoid locked-in subscriptions if possible. I have been bitten too often. I tend to favour different design tools for my own personal work compared to what I am 'forced' to utilize at my jobs. But it depends.
And that is the key phrase here:
it depends.
Let's return to your
@Ambrosia7177 's task requirements and context:
I could use some serious help figuring out if the free version of Affinity Studio will do what I need.
(Don't mind buying standalone software, but am NOT interested in going down the subscription route...)
As others have mentioned here: aside from having to create a Canva account, the core version of Affinity is entirely free. No strings attached (as of yet? Unknown at this time) and Canva has gone to quite extreme lengths to calm their Affinity users that their intention is to keep it freely available for everyone.
The only part users have to pay rent/a subscription for is to access the generative AI features.
But the core application is actually the next FULL release of Affinity Designer, Photo, and Publisher seamlessly integrated into one application with different workspaces to conveniently switch between these three feature sets.
It is also good to mention here that in this version a bunch of long LOOOOONG requested features have finally been implemented. For example it is now possible to convert bitmaps to vectors.
As it stands today: there is no catch. Affinty is fully featured, sans AI functionality. And free. It really is quite impressive if you think about it.
It does NOT save your work to their servers. It does NOT send your files for training their AI. It works locally. Even when users opt for the paid subscription: the AI models are downloaded to your local machine, and run on your local machine.
Here are some things that I need to do in 2026...
For my website:
- Basic photo-editing (e.g. Resize, crop, reduce file-size for web/mobile, adjust light-levels, maybe tweak color)
- Ideally be able to apply adjustments to multiple photos at once. (I can see myself needing more of a production-line versus spending 10 hours editing one photo for the cover of Vogue.)
For YouTube:
- Take screenshots from video, and do basic photo-editing (like above) so a screenshot can be used as cover-photo for a YouTube video.
- Create professional looking YouTube thumbnails. (**Super important)
The Affinity Photo workspace will easily accommodate your listed requirements here. Yours are very basic needs, actually. Because Affinity is now a combined trio of apps, it might come across as cumbersome to learn - but the dedicated workspaces do keep things relatively clutter-free.
GIMP will do just fine as well. The latest version (R3) is actually not that bad (would never have thought to actually write this).
Krita will also work just fine. Amazingly good for digital painting in my opinion, but is also fairly good at general image editing, even if not as performant as dedicated image editors. The only drawback is its text tool, which is okay, but doesn't allow for direct edits on the canvas (yet).
PhotoLine is my preferred general purpose image editing app. A glorious underdog - but not for everyone. And an obscurity on the web and social media. Not great for absolute beginners due to a distinct lack of tutorials.
Pixelmator accomodates your purposes really well too.
If you are reluctant because of the 'free' Affinity deal being a "too good to be true" offer: at this point there is no indication that there are any catches. Of course, you will still need a Canva account, and the software will have to check your license and contact the Canva servers once in a while for you to keep using it. I believe I read that Affinity will need to contact their servers every 7 days, or so, to keep running. But don't quote me here.
For some people this might be a dealbreaker. For most it is not. I mean: quite a few design apps can't even be used anymore without an active live internet connection... (Figma, for example)
Side Note:
I think I have gotten pretty good at shooting (and editing) video in DaVinci Resolve - at least I am proud of my work thusfar.
I really have to ask: if you are already familiar with Resolve: why not also do your photo editing in it? I know people who left Photoshop in favour of Resolve. Of course, it is 'different', but I have edited stills in Resolve myself.
Just grab a frame, place it in its own comp, add text. Use layers, effects. For more complex effects switch to the Fusion workspace. The colour grading workspace allows for high-level colour and light adjustments as well...
Export that one frame to an image. And create your own text/graphics templates to quickly generate new thumbnails for Youtube.
No need for an external image editor.
However, I know that a MAJOR WEAKNESS of mine is not knowing how to make professional-looking YouTube thumbnails.
And the reality is that I am NOT a graphic designer, plus I think that using A.I. to create **fake** Mr. Beast-type YouTube thumbnails is evil.
I do NOT want over-the-top looking thumbnails. Rather, I just want to be able to take a photo (or video clip), maybe swap out the background, add some text, and have it look good enough to make people want to click on my video.
Am hoping that I don't need a Master's degree in art / graphic design to create professional-looking YouTube thumbnails.
This... is something that requires experience and insight in good design and layout. And knowing your audience - what they respond to.
Can't help you with that. Read up on good design. Get a good book on design. Watch some tutorials on what good design is. You need to develop an eye and sense for it - which can't be done in a mere 40 hours.
Learning a new software interface and medium-level usage of software can be easily taught (by oneself or watching/reading tutorials) in 40 hours. Learning how to be a good designer: Nah.
But you can copy designs from other people, of course.
Also not sure WHICH TOOL I need to do this based on my requirements??
I can't tell you which general purpose image editor would work best for you --no-one can. All of the image editors listed above (including Resolve) are overkill for your modest requirements, and it basically comes down to your own preferences: how you want to work, and which software feels 'best' for you personally.
Which means: download and install each (trial), and test for a week, or so. NO-ONE can tell you which will work best for you in this case (in my opinion). We can only suggest options and alternatives, and make you aware of what exists and about different workflows. You decide in the end.
