Exact target精确目标5.00 MB means 5.00 MB5.00 MB 就是 5.00 MB

Verified output已验证结果Passed, Review, or Blocked通过、需复核或已阻止

The moment it is for为这一刻而做

“Your file exceeds the maximum upload size.”“你的文件超过了最大上传大小。”

Your document is ready. The portal is not.文档准备好了，上传平台却没有。

Most compressors optimize one number and leave you to discover whether a form, link, signature, or searchable page disappeared. SendReady treats compression as a document-safety problem—not a race to the smallest file.多数压缩工具只优化一个数字，却把表单、链接、签名或可搜索页面是否消失的问题留给你自己发现。SendReady 把压缩视为文档安全问题，而不是一场比谁文件更小的竞赛。

One calm workflow一套从容的流程

Choose. Compress. Know.选择。压缩。心中有数。

The target, safety mode, document preview, and verification status all stay visible—so there is no mystery between the file you drop and the file you send.目标大小、安全模式、文档预览和验证状态始终清晰可见——从拖入文件到发送文件，中间没有任何黑箱。

Built around trust围绕信任而设计

A compressor with an honest answer.一款会诚实回答的压缩工具。

Aim for the actual limit对准真正的限制

Choose 1, 2, 5, 10, 20, 25, or 50 MB—or enter the exact decimal-MB target your portal accepts.选择 1、2、5、10、20、25 或 50 MB，也可以输入上传平台要求的精确小数目标。

Verify before celebrating确认无误，再说完成

SendReady checks page geometry, text, links, forms, annotations, bookmarks, structure, and rendered similarity after every export.每次导出后，SendReady 都会检查页面尺寸、文字、链接、表单、批注、书签、结构以及渲染相似度。

Refuse a broken success拒绝虚假的成功

Results are marked Passed, Review, or Blocked. If the target is unsafe, the app says so and offers the best verified copy.结果会明确标记为“通过”“需复核”或“已阻止”。目标不安全时，应用会如实说明，并提供已经验证的最佳版本。

Finish the whole batch一次处理整批文件

Drop several PDFs, keep deterministic non-overwriting names, and review each before it leaves your desk.一次拖入多份 PDF，以确定且不覆盖原文件的方式命名，并在发送前逐一检查。

Safe mode means safe安全模式，真的安全

Some limits should be refused.有些限制，本就应该拒绝。

When the requested size would damage the document, SendReady does not paint the result green. It explains the gap, offers the smallest verified copy, and keeps destructive flattening behind a clear choice.当目标大小会损坏文档时，SendReady 不会把结果涂成绿色假装成功。它会解释差距、提供最小的已验证版本，并把有损的扁平化操作放在明确选择之后。

Original file is never overwritten永不覆盖原文件
Safe and flattened workflows are clearly separated安全压缩与扁平化流程清晰分离
Every written candidate is checked again每个输出版本都会再次检查
Review explains exactly what needs attention复核结果会准确说明需要关注之处
