A free batch image upscaler for microstock workflows
Microstock contributors need more than larger files: they need a repeatable way to review quality, keep originals and recover completed work. Pixlift AI offers free batch upscaling with your own GPU runtime and individual results saved to Projects.

Different stock platforms set different rules for enlargement, generative AI, file formats and releases. Check the destination’s current contributor guidelines before processing a collection. A single export setting is not a universal microstock preset.
Adobe’s photo-editing guidance advises against enlarging files. If your goal is Adobe Stock submission, read the separate Adobe Stock guide before deciding to upscale. For any marketplace, larger dimensions alone do not establish quality or eligibility.
Test one image, then use the batch queue
Choose a representative image with fine textures and clear edges. Start with a modest output scale, compare the result at 100%, and look for artifacts. Increase the batch only after the selected model behaves well on your type of content.
Pixlift AI offers 2x, 4x, 8x and 16x dimensions with JPG, PNG and WebP output. Export the format accepted by your destination; PNG and WebP can be useful for other creative workflows, but a platform may require JPEG for photos.
Save completed work while the GPU continues
You do not have to send every result through your browser as it finishes. The connected runtime queues completed images for direct upload to private R2 project storage, and the GPU proceeds to the next image without waiting for that upload.
An image is protected once its upload is verified. If a runtime stops, saved results remain in Projects. Reconnect a runtime and resume the remaining images instead of starting the entire batch again.
Review and download without losing the originals
Projects show small previews for browsing; individual downloads retain the exported image file. A complete batch can also save a ready-made ZIP. If no cached ZIP is available, Cloudflare can package saved results when you download.
Originals stay local until submitted for processing. Keep them backed up: browser storage can be cleared, and a local file edit does not automatically update the cloud project. Missing originals can be selected again and matched by their contents.
Know what is free and what has limits
The Pixlift AI web app has no per-image processing fee. You use a GPU runtime from your own account; its terms, availability, quotas and any charges still apply. Pixlift does not supply unlimited hosted GPU time.
Runtime capacity, output-size limits and available storage affect the size of a practical batch. Check model licenses and source-image rights before using results commercially. This workflow does not guarantee stock-platform acceptance or sales.
