Frequently Asked Questions

Can I use the plugin for free?

Of course! WP Compress allows you to optimize 1,000 images per website – this includes thumbnails as we have to process and optimize them too! If you need more than that, you may upgrade to pro for unlimited images, refer friends to earn additional credits or contact us via the chat box.

Why did you create WP Compress?

We were trying to optimize images and increase page speed within WordPress. When searching for an image optimization solution, we found that our hands were tied anyway we turned.

Any “free” version we tried seemed to be merely a glorified demo, looking to force us into immediately paying up for the Premium version, as features were extremely limited and hard quotas were set to charge per month or per image.

We wanted freedom, and we took it upon ourselves to build a plugin far superior that what was out there, in terms of ease of use and resulting file size while offering first in class free compression credits and the best unlimited plan.

Why should I compress my images?

We’ve all been to that website where the images take FOREVER to load, you start to get antsy. Even with high-speed connections, mobile is becoming more and more popular for accessing the internet and attention spans are becoming shorter and shorter.

Compressing and optimizing your images makes them smaller by removing the excess data that is not needed for web loading, while cutting down file sizes with minimal visible difference.

WP Compress shrinks your images file size, so they load faster, help your PageSpeed Rating and keep your customers on the page, without getting antsy.

What compression settings do you recommend?

We recommend resizing to 2048px and compressing on intelligent mode. Night owl is also highly recommended.
When starting out, leave image backups on. You can restore individual images within 24 hours if needed.

What’s the difference between Compression and Optimization?

Compression is making your image’s file size smaller while optimization is doing so to the point that there is no loss in quality.

We provide both compression and optimization at once, with multiple levels to choose from so your images can load lightning fast while still looking visually pleasing.

How is WP Compress different than other image optimization plugins?

First off, we offer the most FREE image credits out there. We won’t charge you per image, per month, per API call or even impose artificial limits such as maximum file size for basic compression and optimization. While 1,000 images depends on how many thumbnails are generated by your theme, you can earn more to keep it completely free by referring friends and earning additional image credits while unlocking awesome Power Ups.

WP Compress is your COMPLETE solution for image optimization. Although we’re free, we don’t compromise on features or performance.

If you are a high volume or commercial user, we ask that you upgrade to a Professional plan (only $2.99/month) to help support future development and additional server resources needed.

What are PowerUps? How do I earn them?

Power Ups are special unlocks that give you priority access and additional features over everyone else. You can unlock them by referring others to WP Compress to help their images load lightning fast!

Is it really free? How do you sustain that model?

Yes, we aim for WP Compress to be completely free for individuals; however, to prevent abuse we allocate 1,000 image per year (including thumbnails) for non-commercial accounts and monitor the usage.


We encourage you to Upgrade to Pro for unlimited images, priority support, extended cloud backups and even faster compression – annual memberships start at $2.99/month for one site and help cover the costs of servers, maintenance, backups and future updates.

How do I create an account?

Is registration free?

Yes, registration is completely free – we’ll give you 2,500 image optimization credits with no credit card required!

Is it possible to unsubscribe?

Yes, however when you delete the plugin or unsubscribe – you will no longer be able to compress new images.


Why do I need an API Key?

Your API Key is your access pass to WP Compress. It allows your site to securely communicate with our cloud servers and helps route the optimized images back to your website.

The Personal licence allows one website per API key while Professional licenses allow up to 10 sites with unlimited image compression.

You can Upgrade to Pro at any time.

Which image formats can be optimized?

WP Compress can optimize PNGs, JPGs, and GIFs. (Including transparent PNGs, animated GIFs and JPEGs)

If an image format is not accepted, it will be automatically excluded from compression.

Is it possible to use my API Key on more than one website?

Free Tier: One API Key per Website

Unlimited Tier: Based on license: Unlimited image compression for 1, 3, 5, or 10 websites.

Agencies/Resellers: Unlimited Sub-Users each with an individual API key

Is the EXIF data of images removed?

Yes, by default we remove EXIF data to squeeze out the extra savings from your images. If you’d like to save the metadata we offer a toggle in the settings panel.

What happens if I need to compress more than 1,000 images?

At that point, we’ll consider you a high-volume or commercial user. You will need to upgrade to a high-volume plan – starting at $2.99/month for one site.


If you feel that you need more than 1,000 images and are a non-profit or not commercial site, please contact us.

Will the original images be deleted?

The original images will be backed up to assure all goes well with compression and optimization.


The images will be backed up for 24 hours on the free tier allowing you to restore at any point to change the compression level or revert to the original image.


With a Professional License you have 30 days to restore, and cloud storage backups can be purchased.

What is the difference between the Normal, Intelligent and Ultra optimization levels?

Lossless: Highest quality images, minimal savings.
Intelligent: A smart hybrid of smaller file sizes with a limited change in visible quality.
Ultra: Smallest file size – optimized for faster loading times and web quality images.


How does the optimization process work?

We securely send your images to our API, work our magic and send them back to you compressed and optimized to load lightning fast!

Is it possible to re-optimize images with different settings?

Yes! If for some reason you don’t like the way your image looks at a particular level, you may restore the image and compress on a higher or lower setting within 24 hours.

What happens when the plugin is disabled?

When the plugin is deleted, all database tables are also deleted. Your images will stay in their current state – either compressed or uncompressed and you will need to re-install the plugin to make changes.

We recommend keeping the plugin activated and having cloud backups at all times to assure your images are safe and secured.

Does the API use HTTPS?

Yes, we assure all transfers of images are secure and route to the correct sites. We also support your website’s SSL for further security and encryption.
