Permitted and responsible use
Process only material you may lawfully handle
this part of the page begins with a concrete purpose. You remain responsible for ownership, permission, privacy, and the lawful purpose of every source image. Do not use the site to violate rights, evade safeguards, distribute malware, or overload the service. Keeping the purpose visible beside the controls makes the next choice easier to understand and repeat.
A useful result from this practical guidance follows a short, reviewable sequence. Review both the content and technical properties of the output before publishing or submitting it. Do not use the site to violate rights, evade safeguards, distribute malware, or overload the service. Check the displayed measurements before saving or submitting the output somewhere else.
The boundary around the current workflow matters as much as the main feature. The absence of a server upload does not remove your responsibilities for local or downloaded files. You remain responsible for ownership, permission, privacy, and the lawful purpose of every source image. Pixels, file bytes, and newly recovered visual detail are not interchangeable ideas.
For predictable work, keep this documented choice measurable from start to finish. Review both the content and technical properties of the output before publishing or submitting it. The absence of a server upload does not remove your responsibilities for local or downloaded files. Compare the source and preview instead of relying on a vague promise about quality.
Privacy and control belong inside the local browser experience, not in a hidden afterthought. Do not use the site to violate rights, evade safeguards, distribute malware, or overload the service. Review both the content and technical properties of the output before publishing or submitting it. You can replace the source or reset the controls whenever the preview does not suit the requirement.
Current product limits
Operational safeguards, not format definitions
this part of the page begins with a concrete purpose. Current input is capped at 25 MiB; output at 32 MP and 8192 px per dimension. These numbers are present IncreaseImages product limits only, not universal limits of browsers, formats, or images. Keeping the purpose visible beside the controls makes the next choice easier to understand and repeat.

Outputs and third-party requirements
You make the final acceptance decision
this part of the page begins with a concrete purpose. Resizing can interpolate pixels, while file-size adjustment can change encoding quality and dimensions within the product safeguards. Neither operation guarantees restored detail, professional print quality, or acceptance by another service. Keeping the purpose visible beside the controls makes the next choice easier to understand and repeat.

Availability, changes, and liability
A free service can change or pause
this part of the page begins with a concrete purpose. We aim for a useful and accessible service but do not promise uninterrupted or error-free availability. Browser differences, device limits, network delivery, and third-party rules can affect the experience.

The boundary around the current workflow matters as much as the main feature. To the extent permitted by law, use is at your own risk and mandatory consumer rights remain unaffected.

What the browser actually does
IncreaseImages uses browser image APIs rather than a remote enhancement service. That distinction matters: the tool can resample pixels and re-encode a file, but it cannot recreate detail that the source never contained.
Published limits you can verify
- Three static input and output families are supported in this MVP: JPEG, PNG, and WebP.
- Each selected file is limited to 25 MiB before decoding; animated formats and unsupported containers are rejected.
- A generated result is limited to 32 megapixels and 8,192 pixels on either edge to reduce browser memory failures.
| Capability | Current boundary | What it means |
|---|---|---|
| Processing location | This browser | No image file is sent to an IncreaseImages server. |
| Pixel enlargement | Up to 4× per edge | A 2× edge scale creates four times as many pixels. |
| Output encoding | JPEG, PNG, WebP | Actual support is checked before a download is offered. |
Primary sources and method notes
MDN documents that Canvas can create a Blob in a requested image format and that image smoothing is used during scaling. The HTML standard defines these browser behaviors; our numeric limits above are product safeguards reviewed on the stated date. HTML Living Standard: Canvas.
MDN describes the core export step plainly:
MDN Web Docs, HTMLCanvasElement.toBlob()
The HTMLCanvasElement.toBlob() method creates a Blob object representing the image contained in the canvas.

Questions before you resize
Are 25 MiB, 32 MP, and 8192 px universal image limits?
No. They are current safeguards for this product. Other software and formats may support different values, and IncreaseImages may revise its limits when the implementation changes.
Who is responsible for the source image?
You are responsible for having the necessary rights, permissions, and lawful purpose to process it, as well as for protecting sensitive content on your own device.
Is an output guaranteed to be accepted?
No. A destination can apply rules about subject matter, dimensions, byte ranges, metadata, aspect ratio, or format. Check those current rules yourself.
Is the service a backup?
No. Keep the original and any important output in storage you control. Browser state can disappear after a refresh, crash, update, or device cleanup.
